PercentageEasy
If 40% of a number is 520, what is 30% of the same number?
- (A)455
- (B)156
- (C)390
- (D)325
Correct answer: (C) 390
40% of the number is 520, so the number is 520 × 100 ÷ 40 = 1300. Now 30% of 1300 = 1300 × 30 ÷ 100 = 390. Hence the required value is 390.
Shortcut: Scale directly: 520 × 30/40 = 390.
