a person borrows 20000 for 6 years at 8 % p . a . simple interest . he immediately lends it to another person at 9 % p . a . for 6 years . find his gain in the transaction per year .
gain in 6 years = [ ( 20000 ã — 9 ã — 6 / 100 ) â ˆ ’ ( 20000 ã — 6 ã — 8 / 100 ) ] = ( 10800 â € “ 9600 ) = 1200 â ˆ ´ gain in 6 year = ( 1200 / 6 ) = 200 answer a
multiply(20000, divide(const_1, const_100))
