Question
Calculate the value of 'a' if 'P' initially had Rs. 'a'
and invested 45% of this amount in a PF A with a simple interest rate of 35% per annum and the rest in a PF B with a compound interest rate of 30% per annum (compounded annually). After 2 years, 'P' received a total interest of Rs. 3333.6 from both PFs.Solution
According to question; (0.45 × 0.35 × a × 2) + (0.55 × 0.69 × a) = 3333.6 0.315a + 0.3795a = 3333.6 0.6945a = 3333.6 a = 4800
2550.03 ÷ 74.98 x 49.9 = ? + 20.32

1080.04 – 330.18 + 449.98 ÷ 15.06 = ?
150.04% of 800.08 + 20.04% of 749.89 = ? + 322.02
(1709.87 ÷ 38.09) + (768.11 ÷ 23.87) + (6599.81 ÷ 88.06) = ?
(32.15)2 – (255.89)(1/2) – (10648.08)(1/3) = ?
564.932 + 849.029 – 425.08 = 612.095 + ?
1120.04 – 450.18 + 319.98 ÷ 8.06 = ?
