Sonia had a recurring deposit account in a bank and deposited ₹ 600 per month for 2 1 2 years. If the rate of interest was 10 % p.a., find the maturity value of this account.

Given, Monthly instalment, P = ₹ 600 , Time, n = 2 1 2 yr = 2 × 12 + 6 = 30 months, Rate = 10 % . We know the maturity value = P × n 1 + r ( n + 1 ) 2400 , where P is the monthly instalment. Substituting the values of P , n and r in the above equation, we get, Maturity value = ₹ 600 × 30 1 + 10 × 31 2400 = ₹ 18000 2400 + 310 2400 = ₹ 18000 × 2710 2400 = ₹ 20325 Hence, the maturity value of the account is ₹ 20325 .

A car travels a distance of 15 km in 20 minutes . Find the speed of the car in km h - 1 .

Given, Distance travelled, d = 15 km Time taken, t = 20 minutes = 20 60 = 1 3 h Speed of the car in km h - 1 is given by, Speed = Distance time = 15 km 1 3 h Speed = 45 km h - 1 .
