Question 33

Pranita got 30 marks more in Math than what she got in Science. Her Math marks are 60% of the sum of her Math and Science marks. What are her Science marks?

Solution

Let she got $$x$$ marks in Science

=> Maths marks = $$(x+30)$$

According to ques,

=> $$(x+30)=\frac{60}{100}(x+x+30)$$

=> $$(x+30)=\frac{3}{5}(2x+30)$$

=> $$5x+150=6x+90$$

=> $$6x-5x=150-90$$

=> $$x=60$$

=> Ans - (D)
