Mr Sharma wants to choose a investment plan
1. 15% for 5 years(SI)
2. 20% for 3 years(CI)
Which plan will result in higher amount?
My doubt is while doing the calculation for CI I got 1.728 then why are we subtracting it with 1 in order to find which will result in higher amount?
In CAT quotient Number systems test 13 why values of P, Q, R are taken as 5, 7, 9 respectively. Why can't 7, 9, 11 be an answer?
