Why is 8P multiplied by the savings?
latest answer
in Eight P Value of P was derived as 50 hence we multiplied eight with 50 4K income - 7P expense = 50 savings k = 2p so 4 x ( 2P) - 7P = 50 8P - 7P = 50 P = 50 Income is 4k i.e 4 x 2P as K = 2_ so income = 8P = 8 x 50 = 400

How to solve the question 6 and 7
latest answer
Q 6 (1+6%/12)^12 - 1 = 6.16% Q 7 Back work based on answers Since both numbers are round numbers without decimals investment amount is also a non decimal X + X*3*8% = 2688 solve for x like this try for 5%, 4% & 1 % you will get initial investment / principal as 5% at which both P + I for 3 year and 4 year both will match
