### QUANTITATIVE APTITUDE

#### Directions (6-10): Study the following bar diagram and table carefully to answer the questions. Number of employees working in five different companies A, B, C, D and E

 Ratio of male to female employees Company Male : Female A 13 : 6 B 4 : 3 C 7 : 8 D 9 : 11 E 23 : 12

#### (a) 12.5%(b) 16.5%(c) 21%(d) 20%(e) 16%

S1. Ans.(d)
Sol. Total salary of A, B, C, D, and E
= 48250 × 5 = 241250
Statement I Let the salary of B = x
Then, C = 1.5x
Statement II total salary of A and B
= 23500 × 2 = 47000
Then, the salary of A = (47000 - x)
From both statements, we can find the salary of D and E. So, data in both the statements I and II is not sufficient to answer the questions.

S2. Ans.(c)
Sol. From I, cost price
= (640000 - 320000) = 320000
Profit percentage
=320000/320000×100
= 100%
From II, if the cost price = x
Then selling price = 2x
∴ Profit = 2x - x
= i.e. 100%
So, data in statement I alone or in statement II alone is sufficient to answer the question.

S4. Ans.(d)
Sol. From I, x - y = 9
From II, x × y = 0
This can be possible only,
When x = 9
And y = 0
Or, x =0
And y = 9
So, the data in both the statements I and II together are not sufficient to answer the question.

S5. Ans.(e)
Sol. From I , l × b = 252
From II, ratio of length to breadth = 9 : 7
From both statements we can find the perimeter of the rectangle.

S8. Ans.(c)
Sol. Male employees in company A and C = 520 + 336 = 856
Female employees in company B and D = 360 + 352 = 712
∴ Required difference = 856 - 712 = 144

S9. Ans.(d)
Sol. Female employees working in company D = 352
Female employees working in company E = 240
∴ Required ratio =352/240=22/15 or 22 : 15
