Q511.

Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour ?

1)	8	2)	9
3)	10	4)	12
5)	None of these

Answer : 10
Explanation :

Speed of the bus excluding stoppages = 54 kmph

speed of the bus including stoppages = 45 kmph

Loss in speed when including stoppages = 54 - 45 = 9kmph

=> In 1 hour, bus covers 9 km less due to stoppages

Hence, time that the bus stop per hour = time taken to cover 9 km

=distance/speed=9/54 hour =1/6 hour = 60/6 min =10 min

What will Rs. 1000 be worth after three years if it earns interests at the rate of 5% compounded annually ?

1)	1057	2)	1257
3)	1157	4)	1300
5)	None of these

Answer : 1157
Explanation :

A = 1000 x [(11/10) (11/10) (11/10) ]

= Rs. 1000 x1.157 = Rs. 1157

The Compound interest on a certain sum for 2 years is Rs. 410 and simple interest is Rs. 400. The rate of interest per annum is -

1)	5%	2)	6%
3)	6.5%	4)	5.5%
5)	None of these

Answer : 5%

Q515.

The difference between compound interest and simple interest on an amount of Rs. 15,000 for 2 years is Rs. 96. What is the rate of interest per annum ?

1)	6%	2)	8%
3)	9%	4)	12%
5)	None of these

Answer : 8%
Explanation : We know that, P = (Diffrent x 100 x 100) /R²

So, R =√(96 x100 x100 )15000 = 8%

Q516.

There is 80% increase in an amount in 8 years at simple interest. What will be the compound interest of Rs. 14,000 after 3 years at the same rate ?

1)	Rs.3794	2)	Rs.3714
3)	Rs.4612	4)	Rs.4634
5)	None of these

Answer : Rs.4634
Explanation :

Let P = Rs.100

Simple Interest = Rs. 80 ( ∵ 80% increase is due to the simple interest)

Rate of interest = (100�SI)/PT=(100�80)/100�8 =10% per annum

Now let's find out the compound interest of Rs. 14,000 after 3 years at 10%

P = Rs.14000 T = 3 years and R = 10%

Amount after 3 years = P(1+R/100)^T= 14000 (1+10/100)³= Rs.18634

So, C.I = Rs.18634 - Rs.14000 = Rs.4634
