A sum of money becomes Rs 4000 after three years and Rs 8000 after six years on compound interest The sum is .....?
Rs 2000. The amount a after n years of an amount c with interest rate r % is: a = c(1 + r/100)^n After 3 & 6 years of the question there is: Rs 4000 = c(1 + r/100)^3 Rs 8000 = c(1 + r/100)^6 Dividing the second by the first gives: Rs 8000 ÷ Rs 4000 = (c(1 + r/100)^6) ÷ (c(1 + r/100)^3) → 2 = (1 + r/100)^3 Using the first equation and substituting for (1 + r/100)^3 found above: Rs 4000 = c(1 + r/100)^3 = 2c → c = Rs 2000 Alternatively: As it is compound interest, the saved interest also attracts interest; the amount doubles in the 3 years from year 3 to year 6, so it doubles every 3 years. Therefore initially it must be half the value at 3 years → it is ½ × Rs 4000 = Rs 2000.

If 3 bat and 2 shirts cost 1500rsand 2 bats and 3 shirts cost 1375rs find prices of one bat and one shirt?
The first step to this problem is to set up your formulas. 3 bats + 2 shirts = 1500 rs 2 bats + 3 shirts = 1375 rs Then, pick one formula and isolate either one bat or one shirt. Using the second formula, I get: 1 bat = (1375 rs - 3 shirts) / 2 Use this new formula to substitute into the first formula. 3 * ((1375 rs - 3 shirts) / 2) + 2 shirts = 1500 rs Then distribute the 3 through the cost of one bat. (4125 rs - 9 shirts) / 2 + 2 shirts = 1500 rs Now multiply everything by 2 to get rid of the fraction on the left hand side of the equation. 4125 rs - 9 shirts + 4 shirts = 3000 rs Combine like terms. -5 shirts = -1125 rs Solve for cost of 1 shirt, then plug the cost of one shirt back into either of your original formulas to solve for the cost of one bat. Sorry I didn't take the answer all the way to the end, but I figure you should probably do some of your own homework.
