Solutions to Week 13 Quizzes-
Q1 If Roza sells 60 bottles at a 40% discount on the printed price, then she makes 20% profit. Ten of these bottles are destroyed in fire. While selling the rest, how much discount should be given on the printed price so that she can make the same amount of profit?
Solution: Given that if Roza sells 60 bottles at a 40% discount on the printed price, then she makes 20% profit. Ten of these bottles are destroyed in fire.
If she needs to make the same amount of profit by selling the remaining bottles, she needs to sell them at,
⟹ 60 × 0.6x = 50 × ?
⟹ 3.6x = 5 × ?
⟹ ? = 0.72x or she sells at 72% of the printed price.
Therefore the discount to be given = 100 – 72 = 28%
Q2 In a house there is a water storage which is three – fifth full. Pipe A of the storage can fill the storage in 20 minutes and pipe B can empty the storage in 10 minutes.If both the pipes are open,how long will it take to empty or fill the storage completely?
- 6 mins to empty
- 6 mins to fill
- 12 mins to empty
- 12 mins to fill
Pipe B is faster than pipe A and so, the tank will be emptied.
Part to be emptied = 3/5
Therefore, part emptied by (A+B) in 1 minute= (1/10 – 1/20) = 1/20
1/20 : 3/5 = 1: x
3/5 * 20 = 12 mins
So, the tank will be emptied in 12 mins.
Q3 If Aruna is 120% efficient as Buddha who is 80% efficient as Chintu. If Buddha and Chintu assist Aruna on alternate days then they can complete the work in 12 days. What time will be required by Buddha and Chintu together to complete the work?
- 62/5 days
- 62/6 days
- 62 days
- 60 days
Aruna : Buddha = 6 : 5 ……………..(1)
Buddha : Chintu = 4 : 5 ………………..(2)
Taking common ratio’s for both equations we get,
Aruna : Buddha : Chintu = 24 : 20 : 25 ………………..(3)
If Buddha and Chintu assist Aruna on every alternate days which means that,
Work done on day – 1 : 44 units
Work done on day – 2 : 49 units
Work done in two days = 93 units.
Work done in 12 days = 558 units. Time taken by Buddha and Chintu = 558/45 = 62/5 days.
Q4 Two trains start running simultaneously: Train A from Guwahati to Siliguri and Train B from Siliguri to Guwahati, After they meet, the trains reach their destinations after 9 hours and 16 hours respectively. The ratio of their speeds is:
(A’s speed) : (B’s speed)= √b :√a = √16 : √9
= 4 : 3
Q5 A milk vendor has two jars, Jar 1 and Jar 2. Jar 1 contains a mixture of milk and water in 7:2 ratio and Jar 2 contains a mixture of milk and water in 9:4 ratio. In what ratio of volumes should the liquids in Jar 1 and Jar 2 be combined to obtain a mixture of milk and water in 3:1 ratio?
Ratio in which mixtures of Jar 1 and Jar 2 will be mixed
(7A/9 + 9B/13)/ (2A/9+4B/13) = 3/1
On solving we get, A/B = 27/13

Ratio of Actual to Budget in Feb. = 500/200 = 2.5
Ratio of Actual to Budget in Mar. = 900/400 = 2.25
Ratio of Actual to Budget in Apr. = 1150/600 = 1.92
Therefore, the highest ratio is in February.
Q2 b) Predictor is the ratio of sales during Jan-Mar quarter to annual sales (budgeted for current year & actual for previous years). The predictor was highest in?
- Can’t Say
Predictor value in 1998 = 780 / 1600 = 0.4875.
Predictor value in 1999 = 800 / 1310 = 0.6106
Predictor value in 2000 = 900 / 1300 = 0.69
Predictor was highest in 2000.

Q2 The following sentence contains a small paragraph followed by a question on it. Read the paragraph carefully and answer the question given below it. The future of women in India is quite bright and let us hope that they will justify their abilities by rising to the occasion.

The passage best supports the statement that:

- A nation can progress only when women are given equal rights and opportunities as men
- Women ought to be imparted full freedom to prove their worth and contribute to the progress of the nation
