B)580

C)850

D)None of these

1250-400 = 850

**A certain amount of money amounts to Rs. 720 in 2 years and to Rs. 870 in 4(1/2) years. Find the rate of interest if S.I. is reckoned.**

A)12%

B)10%

C)12.50%

D)None of these

Answer –**B)10%**

Explanation :

Trick: (A1*T2- A2*T1) / T2-T1

(720*9/2 )–(870* 2) / ( 9/2) -2

**At what percent per annum will a sum of money triple in 16 years?**

A)12%

B)10%

C)12(1/2)%

D)11(1/2)%

Answer –**C)12(1/2)%**

Explanation :

P = P, SI=2P, T=16

Rate= 100*2P/P*16

**The Simple Interest on a certain sum of money for 3(1/2) years at 16%****p.a. is 60 less than the SI on the same sum for 4(1/2) years at 14% p.a. Find the sum.**

A)Rs.875.14

B)Rs.785.12

C)Rs.857.14

D)None of these

Answer –**C)Rs.857.14**

B)23.8%

C)12.8%

D)None of these

Answer –**B)23.8%**

Explanation :

(4000*8*1)/100 + (8000*13*1)/2*100 +(6000*17*1)/100 + (2000*R*1)/100 =9.13/100 *20000

**A sum was put at S.I. at certain rate for 4 years. Had it been put at 6% higher rate, it would have fetched Rs.800 more. Find the sum.**

A)1333.33

B)3333.33

C)1433.33

D)3033.33

Answer –**B)3333.33**

At 6% higher, increase in SI for 4 years= Rs.800

For 1 year= 800/4= 200

200 is 6% of the sum

1%= 200/6

Sum= 200*100 / 6

**If a sum of money becomes 16 times in 4 years at SI. The rate of interest is**

A)475

B)440

C)650

D)375

Answer –**D)375**

Trick: 100(x-1) / T i.e. 100(16-1) / 4

X= No. of times it becomes

**A certain sum of money amounts to Rs.800 in 2 years and to Rs. 920 in 3 years then the sum is**

A)420

B)680

C)560

D)None of these

Answer –**C)560**

Explanation :

Trick: (A2 – A1)/ T2-T1

(920-800) /1 = 120

P = 800-240 = 560
