Vinay got thrice as many marks in Maths as in English. The proportion of his marks in Maths and History is 4:3. If his total marks in Maths, English and History are 250, what are his marks in English ?

80
Explanation:
M = 3E and M/H = 4/3
∴ H = 3/4 M = 3/4 x 3E = 9/4 E
Now M + E + H = 250
⇒ 3E + E + 9/4 E = 250
⇒ 25 E = 1000
∴ E = 40
M = 3E and M/H = 4/3
∴ H = 3/4 M = 3/4 x 3E = 9/4 E
Now M + E + H = 250
⇒ 3E + E + 9/4 E = 250
⇒ 25 E = 1000
∴ E = 40
