Show Answer

Correct Answer: (2)

Solution: (2)

Boys $\Rightarrow 175 \times \frac{3}{7} = 75$

Girls $\Rightarrow 175 \times \frac{4}{7} = 100$

Boys who read only Hindi $= \frac{75 \times 40}{100} = 30$

Students who read only Sanskrit $= \frac{175 \times 44}{100} = 77$

Girls reading both Sanskrit and Hindi $= \frac{100 \times 32}{100} = 32$

Boys who read Sanskrit only $= \frac{2}{3} \times 45 = 30$

Girls who read only Sanskrit $= 77 - 30$ $= 47$
