1. The discount allowed on an article is rs.960 more than the profit earned on the article. If the selling price of the article is rs.1920 and shopkeeper marked the article 100% above its cost price, then find profit% earned on the article.
10%
20%
12%
18%
40%
Option B
Let cost price of the article = rs.100x
MP = 100x *2/1 = 200x
ATQ, (200x – 1920 ) – (1920 – 100x) = 960
300x = 4800
x = 16
CP = 1600
Profit % = 1920 – 1600/1600 * 100 = 20%

2. The height of cylinder is equal to the side of square. If area of square is 196m^2 and ratio and ratio of radius to height of cylinder is 3 : 2, then find total surface area of such cylinder.
5630
6450
3420
4620
6430
Option D
Side of square = √196 = 14m
height = 14m
radius = 14/7 * 6 = 21
TSA = 2πr ( h + r)
= 2 * 22/7 * 21(14 + 21)
= 4620

3. A man invested rs. P and (P + 350) each at the rate of 20% p.a on CI and SI respectively for two years. If ratio of total CI to total SI received by man is 44 : 75, then find amount invested by man on CI ?
1050
840
450
400
800
Option D
Rate of CI for 2 years = 20 + 20 + 20 *20/100 = 44%
CI received = P * 44/100 = 44P/100
SI received by man = ( P + 350) 40/100 = 40P + 14000/100
44P/40P + 14000 = 44/75
P = 400

4. If three unbiased coins are tossed simultaneously, then find the probability of getting at most two heads ?
3/5
7/8
2/5
4/7
2/17
Option B
Total outcome = 2^3 = 8
favorable outcome = 7
probability = 7/8

5. Pipe A and B alone can fill a tank in 20 hours and 24 hours respectively and outlet pipe C can empty same tank in 40 hours. If three pipes are opened simultaneously in how much time required to fill a empty tank ?
20 hours
15 hours
18 hours
14 hours
28 hours
Option B
LCM of 20, 24 and 40 = 120
efficiency of A = 120/20 = 6
efficiency of B = 120/24 = 5
efficiency of C = 120/40 = 3
time required = 120/(6 + 5) – 3 = 15 hours

6. Directions : What will come in place of questions marks (?) in the following number series ?
