Question

(ii) If 12–% of a certain amount is ? 62.50, find the amount​

Answer 1

→Question: If 12.5% of a certain amount is 62.50. Find the amount?

→Solution:

⇒ Let the required amount be X

→We know that ,  If 12.5% of a certain amount is 62.50

⇒ 12.5% of X = 62.50               ( Convert % to fraction)

⇒ 12.5÷100 × X = 62.50

⇒ 12.5 × X = 62.50

⇒ 12.5X = 6250           ( . is transferred from L.H.S to R.H.S)

⇒ 125X = 62500

⇒ X =   ⁶²⁵⁰⁰⁄₁₂₅

⇒ X = 500

∴ The amount = 500

Answer 2

Answer:

12.5% of X = 62.50               ( Convert % to fraction)

⇒ 12.5÷100 × X = 62.50

⇒ 12.5 × X = 62.50

⇒ 12.5X = 6250           ( . is transferred from L.H.S to R.H.S)

⇒ 125X = 62500

⇒ X =   ⁶²⁵⁰⁰⁄₁₂₅

⇒ X = 500

∴ The amount = 500
