1. The downstream speed and upstream speed of boat is 24 km/hr and 16 km/hr respectively. Then find the total distance cover by boat in still water in 5 hours.
100km
150km
160km
120km
80km
Option A
downstream speed of boat = 24 km/hr
upstream speed of boat = 16 km/hr
speed of boat in still water = 24+16/2 = 20 km/hr
Total distance = 20 * 5 = 100 km

1. The average present age of A and B is 20 hours. After 4 years, age of A will be two times the age of B. Find the age of B after 8 years.
25
14
42
20
32
Option D
Average present age of A and B = 20 years
Total present age = 20 * 2 = 40 years
Let age of A = x years
age of B = 40 – x years
ATQ, (x + 4) = 2( 40 – x + 4)
x + 4 = 88 – 2x
3x = 84
x = 28
present age of B = 40 – 28 = 12 years
age of B after 8 years = 12 + 8 = 20 years

1. When three dice are thrown simultaneously then find the probability that sun of the digits is 16 ?
1/216
5/36
8/36
14/36
1/36
Option E
Possibility = (6,6,4), (6,4,6), (4,6,6), (5,5,6), (5,6,5), (6,6,5)
required = 6
Total = 6^3
Probability = 6/6^3 = 1/36

1. A person spends 20% of his monthly income on food, 40% of remaining on house rent and 50% of remaining on education of children. If he saved rs.4800 from monthly income, then find monthly income of that person.
28000
20000
44000
48000
18000
Option B
Let monthly income of a person = 100x
ATQ, 100x * 80/100 * 60/100 * 50/100 = 4800
24x = 4800
x = 200
monthly income = 100x
100 * 200 = 20000

1. The marked price of the bag is 30% above the cost price and discount allowed on marked price is 20%. If profit earned by selling the bag is rs.120, then find the marked price of the bag.
4200
5000
3200
3900
2800
Option D
Let CP of bag = 100x
MP of bag = 100x * 130/100 = 130x
SP of bag = 130x * 4/5 = 104x
profit = 104x – 100x = 4x
4x = 120
x = 30
MP of the bag = 130 * 30 = 3900
