A took two loans altogether of Rs 1500 from bank B & C. B charged 14% simple interest per annum, while C charged 15% simple interest per annum. If the total interest paid by A in one year was Rs 216, then A borrowed from B & C was?

900 from B and 600 from C

SI = \(\frac{P × R × T}{100}\)

Let the sum borrowed from B is x, and from C is (1500 - x)

Total SI ⇒  \(\frac{x × 14 × 1}{100}\) + \(\frac{(1500 - x) × 15}{100}\) = 216

14x + 22500 - 15x = 21600

x = 900 (from B)           1500 - 900 = 600 (from C)
