- 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% - 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.
56306450342046206430Option D

Side of square = √196 = 14m

height = 14m

radius = 14/7 * 6 = 21

TSA = 2πr ( h + r)

= 2 * 22/7 * 21(14 + 21)

= 4620 - 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 ?
1050840450400800Option 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 - If three unbiased coins are tossed simultaneously, then find the probability of getting at most two heads ?
3/57/82/54/72/17Option B

Total outcome = 2^3 = 8

favorable outcome = 7

probability = 7/8 - 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 hours15 hours18 hours14 hours28 hoursOption 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 - Directions : What will come in place of questions marks (?) in the following number series ?

85, 104, 189, 293, 482, ?875775456565235Option B

The series is, (85 + 104), (104 + 289), (189 + 293), (293 + 482) - 8, ?, 6, 15, 52.5, 236.25
544.52.56Option B

The series is, (* .5), (* 1.5), (* 2.5), (* 3.5), (* 4.5) - ?, 2, 3, 8, 35, 204
24568Option A

The series is, (* 2 – 2), (* 3 – 3), (* 4 – 4), (* 5 – 5), (* 6 – 6), - 27, ?, 159, 324, 555, 852
6086783480Option A

The series is, difference of difference. - 68, 92, 66, 94, 64, ?
84901029686Option D

The series is, (+ 24), (- 26), (+ 28), (- 30), (+ 32)
