Answer 2

Hii dear !!

P = Rs 400
R = Rs 480
T = 4 year

rate of interest = r%
Simple interest (I) = A - P
I = 480 - 400
I = Rs 80
R = ( 100* I ) / pt
r = 100*80 / 400*4
r = 5%

2) if rate of interest increase 2% pa
r = (ptr) / 100
r = ( 400*4*7 )/ 100
r = 114

Therefore,
New Amount = P + I
= 400 + 114
= 514


I HOPE HELP YOU..
