Instead of 52 place 50. - Sahil’s present age is one fourth of his father’s age two years ago. Sahil’s father’s age will be twice Sameer’s age after 10 years. If Sameer’s 12th birthday was celebrated 2 years ago, then what is Sahil’s present age ?
191215917Option D

Sameer = 12+2 = 14

Sahil’s father = x+10 = 2(10+14)

x = 48-10 = 38

Sahil = 36/4 = 9 years - A Shopkeeper marked the price of an item 20% above cost price. He allowed two successive discounts of 20% and 25% to a customer. As a result he incurred a loss of Rs.812. At what price did he sell the item to the customer?
29002144193020881893Option D

CP = 100

MP = 120

120*80/100 = 96; 96*75/100 = 72

Loss = 100 – 72 = 28%

CP = 100/28*812 = 2900

SP = 2900*72/100 = 2088 - A father left a will of Rs.35 lakhs between his two sons aged 8.5 and 16 such that they may get equal amounts when each of them reach the age of 21 years. The original amount of Rs.35 lakhs has been instructed to be invested at 10% p.a. SI. How much did the elder son get at the time of the will?
Rs.25 LakhsRs.29 LakhsRs.21 LakhsRs.18 LakhsRs.24 LakhsOption C

Let x be the amount of elder son at the time of will & Younger son’s amount at the time of will (350000 -x)

For elder son, T= 21-16=5

For younger son, T=21-8.5= 12.5

Amount Should be equal so,

x + [(x*10*5)/100] = (3500000-x) + [((3500000-x)*10*12.5)/100]

=> 5x/3 = 3500000

x = 2100000 - Zishan and Rohit invested in a partnership business. Zishan invests Rs. 70,000 for 8months and Rohit invests Rs. 84,000 for 10 months. Out of a profit of Rs. 63140, Zishan’s share is:
Rs. 20000Rs. 23749Rs. 20486Rs. 25256Rs. 29648Option D

Ratio of their shares = (70000 * 8) : (84000 * 10) = 2 : 3

Zishan’s share = Rs.63140 * 2/5 = Rs. 25256 - Two cards are drawn at random from a pack of 52 cards. What is the probability that either both are black or both are jacks?
55/22757/22349/22153/22055/221Option E

Case 1: both are black

26C2/52C2

Case 2: both are jack

4C2/52C2

Add both cases.

But now 2 black jacks have been added in both cases, so subtracting their prob. : 2C2/52C2

325/1326 + 6/1326 – 1/1326 = 55/221
