Question

in how many years will a sum become triple of itself at the rate of 12% p.a?
​

Answer 1

Step-by-step explanation:

let the P = x

so, A = 3x

so,SI = 3x - x

= 2x

R = 12%

T = SI×100/P×R

T = 2x ×100/x×12

T = 2×100/12

T = 100/6

T = 16.66

Answer 2

Answer:

P=x

A=3x

SI=A-P

3x-x=2x

R=12%

T=SI *100/P*R

=2x*100/x*12

=50/3years
