1.
7(1/3) x 3(3/5) % 3(3/4)
=> 22/3 x 18/5 % 15/4
=> 22/3 x 18/5 x 4/15 = 176/25 = 1(1/25)
2.
41 + √5184 % 9 = ?2
=> 41 + (72/9) = ?2
=> ?2 = 41 + 8 = 49
=> ? = 7
4.
37%of ? = 3118.73
=> ? = 3118.73 x (100/37) = 8429
5.
15912 % 34 % 6
=> 15912 x (1/34) x (1/6) = 78
6.
5(1/3) x 2 (3/5) + ? = 53
=> (16/3) x (13/5) + ? = 53
=> ? = 53 - (208/15) = 587/15 = 39(2/15)
7.
4/9 of 3/7 of 5/8 of 1512
=> (4/9) x (3/7) x (5/8) x 1512 = 180
8.
(24 x 3 + 4 x 5) / ( 132 % 6 x 4)
=> (72 + 20) / (22 x 4) = 92 / (22 x 4) = 23/22 = 1 (1/22)
9.
62.5% of 440 + 36% of 175
=> ((62.5 / 100) x 400) + ((36/100) x 175)
=> 275 + 63 = 338
10.
(134.56 / ?) = (? / 25)
=> ?2 = 134.56 x 25 = 3364
=> ? = √ 3364 = 58
Shortcut :
(134.56 / ? ) = (? / 25)
=> ? = √ 134.56 x √ 25
=> ? = 11.6 x 5 = 58
11.
Ratio of A, B and C = 11:5:7
C gets 7 parts and B gets 5 parts. Therefore C gets 2 parts more than B
Actually, C gets Rs. 860 more than B
So, 2 parts = Rs. 860
Total money (23 parts) = (23/2) x 860 = Rs. 9890
12.
Student marks = 196
Additional marks required to pass = 14
Total marks required to pass = 196 + 14 = 210
Required pass percentage = 35%
So, 35%= 210
100% (total aggregate marks) = (100/35) x 210
=600
13.
Amount = 140% of 104% of 12500
=> (104/100) x (104/100) x 12500 = 13520
So, compound Interest = 13520 - 12500 = Rs. 1,020
14.
Let the number of cylinders that can be made be 'x'
Volume of sphere = (4/3).PI.r3
Volume of cylinder = PI.r2.h
So, (4/3).PI.r3 = PI.r2.h x X
= (4/3) PI (9)2 = PI (3)2 x 4 x X
=> X = 3
15.
Let the length of the bridge be 'X' m
So 475m + x = 75 x (5/18) mps x 36 sec
So, 475 + x = 750 m => x = 275 m
16.
Average Qualified students
= (18 + 24 + 30 + 32 + 50) / 5 = (154/5) = 30.8
So, two years above the average
18.
Required percent = ((40-35)/40) x 100 = 12.5%
19.
Required ratio = 24 : 32 = 3:4
