Question
Arjun made two investments: the first was Rs. 1,600 at
an annual simple interest rate of R% for a period of 2 years, and the second was Rs. 2,000 at an annual simple interest rate of (R + 5)% for 3 years. The total interest he earned from both investments combined was Rs. 1,772. Calculate the value of R.Solution
According to question; 1600 × R/100 × 2 + 2000 × (R + 5)/100 × 3 = 1772 32R + 60R + 300 = 1772 92R = 1472 R = 16
(804/65) ÷ (11/798) × (129/131) = ?
1254.04 – 440.18 + 399.98 ÷ 10.06 = ?
( 19.95%  of 799.89 ) × 12.05 = ? 2 + 18.99 × 6250 ÷ 1250
