Solution 1. Let us suppose one Part is x and other part is y. As per given condition(4/7)x = (2/5)yOr 10x = 7y Or x = (7/10) y As x and Y are two parts of number so their sum will be equal to that number. Hence x + y = 34or (7/10) y + y = 34 Or 17 y = 340 Or y = 20 And x = 34-20 = 14Hence correct option is d. Solution ...
