Question
A number reduced by 33% becomes 335. What percent should
it be increased so that it becomes 950?Solution
Let the number be x, then x × (67/100) = 335 ⇒ x = 335 × (100/67) ⇒ x = 500 If number become 950, then number increased by = 950 – 500 = 450 ∴ Percentage increased by = 450/500 × 100 = 90%
