Question

in how much time will a sum of money amounts to 4 by 3 of itself at 13 whole 1 by 3% per annum​

Answer 1

Answer:

n =2.5

Step-by-step explanation:

P becomes 4/3P at 13 1/3%p.a

4/3P = P(1+n×40/3×1/100)

4/3 = (1+40n/300)

4/3 = (300+40n/300)

4×300/3 = 300 +40n

400 = 300+40n

100 = 40n

n = 2.5
