A Product is supported each week by the same three Product supporters. Last month the first supporter took 440 calls, the second took 360 calls, and the third took 300 calls. This month the job will consists of 1500 calls. If the three supporters each increase their work proportionately, how many more calls will the second supporter take this month than last month ?
Options- A. 131 calls
- B. 160 calls
- C. 491 calls
- D. 600 calls
- Correct Answer
- 131 calls
Explanation1st supporter recieve 440 calls
2nd supporter recieve 360 calls
3rd supporter recieve 300 callsSo total calls = 1100 calls ;
Calls this month= 1500
So remaining calls to be distributed is 400So Now Ratio 1st:2nd:3rd ==> 440:360:300
=> 22:18:15Now No. of More Calls 2nd supporter will get => [18/(22+18+15)] x 400
=> (18/55) x 400
=> 131 Calls
So 131 more Calls than last month. - 1. On her deathbed, a grand mother called upon his three grand sons and told them to distribute all her assets worth Rs. 52,500 in the ratio of 1/35 : 1/21 : 1/15 amongst themselves. Find the smallest share amongst the three portions ?

Correct Answer: Rs. 10,500
Explanation:
The ratio of distribution should be:
21 x 15 : 15 x 35 : 35 x 21
= 315 : 525 : 735
= 3 : 5 : 7
The smallest share will be of worth:
3/15 x 52,500 = Rs. 10,500
Correct Answer: 54
Correct Answer: 32
Explanation:
Given ratio of number of sheep and horses = 4 : 15
Let number of sheep and horses are 4k and 15k
Number of horses = 13200/110 = 120
Now 15K = 120 and k = 8
Number of sheep = 4k = (4 x 8) = 32
Correct Answer: 10 points
Explanation:
a:b = 60:40
a:c = 60:45
c/a x a/b = 45/60 x 60/40 = 45/40 = 90/80
So C gives B => 10 points.
Correct Answer: 165
Explanation:
Ratio C1:C2 = 3:5 and C2:C3 = 7:11
So C1:C2:C3 = 21 : 35 : 55
Let the strength of three classes are 21x, 35x and 55x respectively, then
Given that 21x + 35x + 55x = 333
=> 111x = 333 or x=3
So strength of the class with highest number of students =55x = 55x3 = 165.
Correct Answer: Rs. 1595.14
Explanation:
Ratio of the share of a lady, a gents and a girl is 7 : 4 : 3
No of ladies, gents and girls are 5, 3, 3
Thus effective ratio of ladies, gents and girls is 7 x 5 : 4 x 3 : 3 x 3 = 35 : 12 : 9
so part of gents = (12/56) x 7444 = Rs. 1595.142
so part of 1 gents = 1595.142/3 = Rs. 531.71.
Correct Answer: 9
Explanation:
Here the number of cogs is inveresly proportional to number of revolutions
=> More cogs less revolution
=> 6 : 14 :: x : 21
=> (21x6)/14 = 9
Correct Answer: 150, 200
Explanation:
The incomes of A and B be 3P and 4P.
Expenditures = Income - Savings
(3P - 100) and (4P - 100)
The ratio of their expenditure = 1:2
(3P - 100):(4P - 100) = 1:2
2P = 100 => P = 50
Their incomes = 150, 200
Correct Answer: 1 : 4 : 6
Correct Answer: 3:2:4
Explanation:
Given, y/(x - z) = (y + x)/z = x/y
Also
Using (1) and (2), we get yz = xy - yz +
2yz = xy +
2z = x + y
Only option (B) satisfies the equation.
