The bar graph below shows the output of five carpenters over one month, each of whom made
different items of furniture: Chairs, tables, and beds.

**A. ** Only i

**B. ** Only ii

**C. ** Both i and ii

**D. ** Neither i nor ii

**Answer : ****Option C**

**Explaination / Solution: **

(i) The number of beds made by carpenter C2 is exactly the same as the number of tables made by carpenter C3

Consider the following statements.

i. The number of beds made by carpenter C2 is exactly the same as the same as the number
of tables made by carpenter C3.

ii. The total number of chairs made by all carpenters is less than the total number of tables.
Which one of the following is true?

(i) The number of beds made by carpenter C2 is exactly the same as the number of tables made by carpenter C3

i.e., beds made by carpenter C2 = 8 = tablesmade by carpenterC3 [From the bargraph] So,(i) is correct.

(ii) Total Number of tables made by all carpenters=31.
Total Number of chairs made by all carpenters=23

23 < 31
(ii) is correct

The current erection cost of a structure is Rs. 13,200. If the labour wages per
day increase by 1/5 of the current wages and the working hours decrease by
1/24 of the current period, then the new cost of erection in Rs. is

**A. ** 16,500

**B. ** 15,180

**C. ** 11,000

**D. ** 10,120

**Answer : ****Option B**

**Explaination / Solution: **

Let ‘W’ be the labour wages, and ‘T’ be the working hours.

Let ‘W’ be the labour wages, and ‘T’ be the working hours.

Now, total cost is a function of W ×T

Increase in wages = 20%

∴ Revised wages = 1.2 W

Decrease in labour time = (100/24)%

Re vised time = (1- (1/24))T = 23/24 T

Re vised Total cost = 1.2 × (23/24)WT = 1.15 WT

= 1.15 × 13200 = 15180
