a) 64
b) 24
c) 36
d) 48
e) None of these
Answer »Answer: (d)
Total number of shirts sold on weekdays
= (14 + 16 + 12 + 22 + 18)% of x
= 82% of x
Total number of shirts sold on weekends
= (100 – 82)% of x

According to the question
18% of x = 72
⇒ x = 400
Number of formal shirts sold = Total number of shirts sold – Number of casual shirts sold
| Day | Percentage of total shirts sold | Total number of casual shirts sold | Number of formal shirts sold |
| Monday | 14% | 32 | 24 |
| Tuesday | 16% | 24 | 40 |

According to the question
18% of x = 72
⇒ x = 400
Number of formal shirts sold = Total number of shirts sold – Number of casual shirts sold
| Day | Percentage of total shirts sold | Total number of casual shirts sold | Number of formal shirts sold |
| Monday | 14% | 32 | 24 |

Answer »Answer: (e)
Total number of shirts sold on weekdays
= (14 + 16 + 12 + 22 + 18)% of x

Total number of shirts sold on weekends

= 18% of x
According to the question

| Monday | 14% | 32 | 24 |
| Tuesday | 16% | 24 | 40 |
| Wednesday | 12% | 28 | 20 |
| Thursday | 22% | 56 | 32 |
| Friday | 18% | 20 | 52 |
The number of casual shirts sold on Monday and Wednesday together
= 32 + 28 = 60
The number of formal shirts sold on Tuesday and Thursday together
= 40 + 32 = 72
Hence, the required ratio = 60 : 72
= 5 : 6
Question : 94 [IBPS-PO-Prelims-2020]

= 18% of x
According to the question
18% of x = 72
⇒ x = 400
Number of formal shirts sold = Total number of shirts sold – Number of casual shirts sold
| Day | Percentage of total shirts sold | Total number of casual shirts sold | Number of formal shirts sold |

| Tuesday | 16% | 24 | 40 |
| Wednesday | 12% | 28 | 20 |
| Thursday | 22% | 56 | 32 |
| Friday | 18% | 20 | 52 |
The number of shirts sold of brand X on Friday
= 40% of 20 + 25% of 52
= 8 + 13 = 21
Hence, the required number of shirts sold
= (20 + 52) – 21
= 72 – 21 = 51.
