Question

The ratio of marks of Rohan in English to SST is 3:4 if he has secured 75marks in English , then Find his marks in SSt​

Answer 1

Let the marks obtained in S.St be 'x'

Then,

$\frac{3}{4} = \frac{75}{x} (cross \: multiply) \\ 3x = 300 \\ x = \frac{300}{3} \\ x = 100$

Hence, the marks obtained by Rohan in S.St is 100

!!!!!!!! Mark as brainliest !!!!!!!!

Answer 2

Ratio is 3:4

English marks are 75

Acc.to proportional method. Let x is the marks in SST

3:4 :: 75:x

P.O.E=P.O.M

3 multiplied by x = 75 multiplied by 4

3x = 300

x = 100

:) Marks in SST are 100.
