Answer:
29,000
Step-by-step explanation:
[1.] Principal = 3600
Amount = 5220
Time = 5 years
Interest = 5220-3600 = 1620
Take principal amount to be 100
Interest of Rs 100 in 1 year = 1620*100/3600*5
= Rs 9
Therefore, rate of interest = Rs 9 per annum
[2.] Amount = 47270
Time. = 7 years
Rate = 9 per annum [from 1]
Interest of Rs 100 in 1 year = Rs 9
Interest of Rs 100 in 7 years = 9*7= 63
With Rs 100 as principal, amount = 100+63=163
In 7 years amount being 163 the principal would be 100
If we take Rs 1 as principal, amount = 100/163
Therefore, If amount is = 47270,
Principal = 100*47270/163
= ( 163*29 = 4727)
= 290*100
= 29000
