Slot – 1 – Quantitative Aptitude – Interest – Veeru invested Rs 10000 at 5% simple annual interest


Q. Veeru invested Rs 10000 at 5% simple annual interest, and exactly after two years, Joy invested Rs 8000 at 10% simple annual interest. How many years after Veeru’s investment, will their balances, i.e., principal plus accumulated interest, be equal?
Answer: 12

Solutions:
Equating balance and intrests
[10000*5*(x+2)/100]+10000 = [8000*10*x/100]+8000
500*(x+2) +10000-8000=800*x
1000 + 2000=800x-500x
3000=300x
X=10 years
Veerus investment was made x+2 years ago.So we get 12 years
