The simple interest on an amount of Rs. x at an annual
rate of 4% for 3 years is Rs. 120 less than the simple interest on an amount of Rs. (x – 800) at an annual rate of 8% for 2 years. Determine the value of x.Solution

?% of (112.31 ÷ 13.97 × 90.011) = 359.98
40.22 of 249.98% + 459.99 ÷ 23.18 = ?
456.9 + 328.10 - 122.98 = ? + 232.11
