11426.When you reverse the digits of age of father u will get the age of son. One year ago the age of father was twice that of sons age. What are the current ages of father and son?
72, 27
62, 26
63, 36
73, 37
Explanation:

Ongoing through the options, Let current Father age = 73; Sons age = 37and, f = fathers age and s = sons age.

Then, according to the question,

f = 10a + b and s = a + 10b;

=> f - 1 = 2(s - 1) so

=> f = 2s - 2 + 1

=> f = 2s - 1

Therefore,

10a + b = 2a + 20b - 1

8a = 19b - 1, making a = 7 and b = 3.

So Father is 73 and son is 37. (Last year f = 72, s = 36)

11427.A number is to be multiplied by the fraction 4/5. But Amit, by mistake multiplied it by 5/4 and obtained the number 81 more than the correct value. What was the original number?
200
240
180
120
Explanation:

Let the number be x.

According to the question,

=> x $\times$ 5/4 - x $\times$ 4/5 = 81

=> x $\times$ (25 - 16)/20 = 81.

=> x $\times$ 9/20 = 81.

=> x = 180.

11428.A cube has a volume of 512 cubic meters. If each side is doubled in length what will be its new Volume in cubic meters?
5000
5182
6897
4096
Explanation:

If x is side of original cube, then $x^3$ = 512

When each side is doubled,

Then vol = $(2x) ^3$ = $8x ^ 3$ = 8 $\times$ 512 = 4096 cubic mtr.

11429.A car left from a Place A at 8.12 am and reached the Place B, 180 miles distant at 11.57 am. What was its average speed in miles per hour?
45 miles/hr.
70 miles/hr.
48 miles/hr.
60 miles/hr.
Explanation:

Given, total distance=180 miles.

Time = 3hrs 45 min = 15/4hrs.

Average speed = Total Distance / Total Time = 180/(15/4) = 48 miles/hr.

11430.If the average of three numbers is 135 and the difference between others is 25 then find the lowest number.
110
120
130
None of these
Explanation:

Average of 3 number is 135.

=> (x + y + z) / 3 = 135

Given Difference between 2 values is 25. So,

=> x = y - 25

=> z = y + 25

=> [(y-25) + y + (y+25)]/3 = 135

=> [y-25 + y + y + 25] / 3 = 135

=> 3y/3 = 135

=> y = 135

So, x = 110; y = 135; z = 160

Hence, the lowest number is 110.

11431.In a competitive exam, Ram got 10% less than Shyam who got 25% more than Mohan and Mohan got 20% less than Jawa. If the total marks were 500 and Ram got 360.What was Javas percentage?
80
64
72
None of these
Explanation:

Given, marks of Ram = 360.

Then, according to the given data,

=> 360 = 90% of Shyam

=> Shyam = 360 * 10 /9 = 400

And, Shyam = 125% of Mohan

=> 400 = 125/100 $\times$ Mohan

=> Mohan = 400 $\times$ 100/125 =80 $\times$ 4= 320

Mohan = 80% of Java.

=> 320 = 80/100 $\times$ Java

=> Java = 320 $\times$ 100 / 80 = 400

Therefore, Javas percentage = 400/500 $\times$ 100 = 80%.

11432.A and B can do a piece of work in 18 and 9 days respectively. A does the work for a few days and left, then B continued for 6 days. How many days did A and B work together ?
5 days
8 days
3 days
2 days
Explanation:

According to the question,

A`s 1-day work = 1/18

B`s 1-day work = 1/9

(A+B)`s 1-day work = 1/18 + 1/9 = 3/18. [1 work in 18/3 = 6 days]

B continued for 6 days,

So, B`s 6 days work = 6/9

Total work done by A + B together = (1-6/9) = 3/9

Hence, A+B do 3/18 work in 1day (from above)

1 work in 18/3 day = 6 day

So,3/9 work in (6 $\times$ 3/9) = 2 days

So, both A and B worked for 2 days.

11433.A person walks on a plain land at 4 km/hr. and up the slope at 3 km/hr. and comes down at 6 km/hr. and walks on the plain land again at 4 km/hr. if he started at 3:00 pm and comes back at 9:00 pm. What is the one-way distance?
24 km
12 km
10 km
None of these
Explanation:

Given, his speed on plain and upward was 3km/hr. and 4 km/hr.

Average speed a = 24/7.

When he was coming back his speed was 6km/hr. and 4 km/hr.

Average = b = 24/5.

So Overall average speed v = 4 km/hr.

Given, time = 6hr (i.e. from 3pm to 9 pm)

Now, v = d/t

=> d=v $\times$ t

=> d=4 $\times$ 6=24km (two-way distance)

Therefore, one-way distance = 12 km.

11434.A and B started a business in partnership investing Rs 20000 and Rs 15000 respectively. After six months C jointed them with Rs 20000. What will be Bs share in the total profit of Rs 25000 earned at the end of two years from the starting of the business?
6500
7500
8000
None of these
Explanation:

According to the question,

Ratio of their investment will be A:B:C = (20000 $\times$ 24): (15000 $\times$ 24): (20000 $\times$ 18) = 4: 3: 3

Then, Bs Share = (3 $\times$ 25000)/ (4 + 3 + 3) = 7500.

5th
9th
12th
13th
Explanation:

Number of boys in the row = (15 + 4 + 3) = 22. C is just left of A. So, C is 14th from the left end.

Number of boys to the right end of the row. So, C is 9th from the right end of the row.

11441.Clocks & Calendars:A clock is set right at 6 a.m. The clock loses 16 minutes in 24 hours. What will be the true time when the clock indicates 10 p.m. on 4th day?
12 am
06 am
11 p.m.
10 p.m.
Explanation:

Time from 5 a.m. on a day to 10 p.m. on 4th day = 89 hours.

Now 23 hrs. 44 min. of this clock = 24 hours of correct clock.

356/15 hrs. of this clock = 24 hours of correct clock.

89 hrs. of this clock = (24 x 31556 x 89) hrs. of correct clock.

= 90 hrs. of correct clock.

So, the correct time is 11 p.m.
