Find the simple interest on Rs. 5a2b2 for 4ab years at 7b% per annum
Advertisements
Solution
Simple interest = `("Principal" xx "years" xx "rate of interest")/100`
= `(5"a"^2"b"^2 xx 4"ab" xx 7"b")/100`
= `((5 xx 4 xx 7)("a"^2 xx "b"^2 xx "a" xx "b" xx "b"))/100`
= `140/100 ("a"^2"b"^4)`
= `14/10 "a"^3"b"^4`
Simple interest = `7/5 "a"^3"b"^4`
