solve fast plese...................

Answer 1

Hey!

Here is your Answer!

 let principal amount be P
then
sum of amount for 4 years

4800 = p +p×r×t/100
4800= p+ (p×r×4)/100

taking LCM 100
100p + 4pr= 480000............(1)

now for 5 years

5250 = p+(p×r×5)/100
100p +5pr = 525000................(2)

solve 1 & 2

pr = 45000

Now interest for 2 years

Si = prt/100
si = 45000×2/100
si = 900 Ans!

Hope it's helpful ✌✌
