Mr.Jonathan invested Rs. 18,500 divided into two different schemes, A and B, at S.I of 15% and 12.5% respectively. If the total amount of the simple interest earned in 2 years is Rs. 5225, what was the amount invested in scheme A? (In Rs.)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 12000.

Let investment in A = x

(x×15×2)100+(18500−x)×12.5×2100=5225{(x × 15 × 2)\over100}+\frac{(18500 - x) × 12.5 × 2}{100}=5225

⇒ 0.3x + 0.25(18500 - x) = 5225

⇒ 0.3x + 4625 - 0.25x = 5225

⇒ 0.05x = 600

⇒ x = 600/0.05 = 12000
