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?
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)
