A sum of money, when invested at the rate of 15% per annum at simple interest, amounts to ₹26,000 in 2 years. What is the simple interest that accrued during these 2 years?

₹6,000

Simple interest for 2 years = 2 × 15% = 30%

Let initial sum invested = 100%

Amount = Principal + Interest

= 100% + 30%

= 130%

ATQ,

130% = 26000

1% = \(\frac{26000}{130 }\) = 200

Simple interest of 2 years = 30% = 30 × 200 = Rs. 6000
