Question

anil scored in mathematics is 5 / 6 of mark scored in science . the score in social is 4 / 5 of more cored in mathematics . if the total marks is 225 , then the marks scored in mathematics is
​

Answer 1

let the marks scored in science be X.

$in \: math =x \times \frac{5}{6} = \frac{5x}{6}$

$in \: sst = x \times \frac{5}{6} \times \frac{4}{5} = \frac{2x}{3}$

A/Q,

$x + \frac{5x}{6} + \frac{2x}{3} = 225$

$\frac{15x}{6} = 225$

$15x = 225 \times 6$

$15x = 1350$

$x = \frac{1350}{15}$

$x = 90$

$science \: score = 90$

$math \: score = \frac{5x}{6} = \frac{5 \times 90}{6 } = 75$
