If the compound interest on a sum for 2 years at 12.5 p.a is Rs.510, the simple interest on the same sum at the same rate for the same period of time is__
- 400
- 450
- 480
- 510
- option3
Clear All
C.I = S.I[1+ (r/200)] for 2 years
therefore, 510=S.I[1+(12.5/200)]
510=S.I * 17/16
S.I=30 * 16 = 480

Let his expense be 100
Income = 120
Savings = 20
New income = 120 + 60% of 120 = 192 New Expense = 100+ 20% of 10= 120
New savings = 72
% increase in his savings
= (72-20/20*100=52*5= 260%

Let the number of 100p, 25p, 50p coins be 4x, 9x, 5x respectively. Then, (Since, 25p = Rs 1/4, 50p = Rs 1/2) => 16x + 36x + 10x = 420(Multiplying by 4 which is the LCM of 1,4, 2) => 35x = 420 => x = 12. Therefore,
No. of 10p coins = 4 x 12 = 48,
