1-5: There are four companies, namely AA, BB, CC, and DD. The following table shows the total cost and total sales of these companies for their different products.
For companies BB and DD, the ratio of sales to asset is same and equal to 3. However, sales of company BB is half that of company DD. Profit of company CC is 25% which is also equal to two-thirds of the profit of company AA.
Profit of company BB is same as that of company AA which amounts to 25% of BB sales. Cost of company DD is twice the sale of company CC.
AA | BB | CC | DD | |
Sales | 1,00,000 | – | – | – |
Cost | – | – | 1,00,000 | – |
Profit | – | – | – | – |
Assets | 25,000 | – | 35,000 | – |
- What are the assets of DD company?
A) Rs 37,500
B) Rs 1,25,000
C) Rs 1,00,000
D) Rs 2,50,000
E) None of these
C) Rs 1,00,000
Explanation:
For the questions to be answered, first complete the table based on given information.
Cost of CC is 1,00,000 and given that the profit % is 25%, so sales of CC = 125/100 * 1,00,000 = 1,25,000. This means profit of CC = 1,25,000 – 1,00,000 = 25,000
Profit of CC is two-thirds of the profit of company AA, so profit of AA = 3/2 * 25,000 = 37500. Sales of AA = 1,00,000. So cost of AA = 1,00,000 – 37,500 = 62,500
Profit of BB = Profit of AA = 37,500. Also, profit of BB = 25% of sales of BB. So, 37,500 = 25/100 * sales of BB. So, sales of BB = 1,50,000. This gives cost of BB = 1,50,000 – 37, 500 = 1,12, 500.
Cost of DD is 2 times sales of CC. So, cost of DD = 2 * 1,25,000 = 2,50,000. Given sales of BB is half of DD. So, sales of DD = 2 * 1,50,000 = 3,00,000.
And so on find remaining missing parts.

- What is the cost of company CC?
A) Rs 37,500
B) Rs 1,25,000
C) Rs 1,00,000
D) Rs 2,50,000
E) None of these
C) Rs 1,00,000 Explanation:
See the value from the table - What is the profit percentage of company DD?
A) 20%
B) 25%
C) 28%
D) 30%
E) None of these
A) 20%
Explanation:
Profit% = 3,00,000 – 2,50,000/2,50,000 * 100 - What is the ratio of the profits of company CC to company DD?
A) 1 : 3
B) 2 : 1
C) 1 : 2
D) 6 : 5
E) None of these
C) 1 : 2
Explanation:
25,000 : 50,000 - A completes a piece of work in 10 days, and B completes the same work in 18 days. Both A and B started the work, but A left after some days. Now B completed the remaining work in 6 4/5 days. Find the number of days after which A left?
A) 2 days
B) 3 days
C) 4 days
D) 5 days
E) None of these
C) 4 days
Explanation:
Let A left after ‘x’ days. B completed remaining work in 6 4/5 days or 34/5 days. So,
(1/10 + 1/18) * x + 1/18 * 34/5 = 1
(1/10 + 1/18) * x = 1 – 17/45
14/90 * x = 28/45
Find x - A bottle contains a mixture of alcohol, acid and water in the ratio 1 : 2 : 3, while another bottle contains the same in the ratio 2 : 3 : 4. If both the solutions are mixed in the ratio 5 : 9, then the percentage of acid in the final solution is
A) 33 1/3 %
B) 33%
C) 50%
D) 28%
E) None of these
A) 33 1/3 %
Explanation:
Ratio of acid to alcohol+water in 1st solution = 2 : (1+3) = 1 : 2
Ratio of acid to alcohol+water in 2nd solution = 3 : (2+4) = 1 : 2
They are mixed in ratio 5 : 9
So ratio of acid to alcohol+water in final solution = 1/3 * 5 + 1/3 * 9 : 2/3 * 5 + 2/3 * 9 = 1 : 2
So, percentage of acid = 1/(1+2) * 100 = 100/3 %
- Find out the number of words consisting of 3 consonants and 2 vowels out of 8 consonants and 3 vowels available.
A) 1050
B) 168
C) 20160
D) 25200
E) None of these
C) 20160
Explanation:
For consonants = 8C3 and for vowels = 3C2
And for 5 words arrangement = 5!
So total 8C3 * 3C2 * 5!
- 10, 8, 13, 35, 135, 669, ?
A) 1500
B) 1890
C) 3678
D) 4007
E) 4070
D) 4007
Explanation:
10*1 – 2, 8*2 – 3, 13*3 – 4, 35*4 – 5,…., 669*6 – 7
- x^{2} = 1369; y = √1369
A) x ≤ y
B) x ≥ y
C) x > y
D) x < y
E) No relationship
A) x ≤ y
Explanation:
x^{2} = 1369
x = 37, -37
y = √1369
y = 37
put on number line
-37 37
When y = 37, y ≥ x
So y ≥ x
