1
What is the ratio of the number of books sold by shop La and Na together to the number of pens sold by shop Pa and Na?
» Explain it
A
Number of books sold by shop La and Na = 105 + 110 = 215

Number of Pens sold by shop Pa and Na = 80 + 90 = 170

Ratio = 215 : 170 = 43 : 34

Hence, option A is correct.

2
If the total profit earned by all the shop by selling the eraser is Rs 735, find the total profit earned by Shop La and Shop Pa after selling the eraser. (If the cost price and selling price are equal for all the erasers.)

Total eraser sold by all the shops = 65 + 95 + 85 = 245

Profit earned on 1 eraser =  735  = Rs. 3
245

Total eraser sold by Shop La and Shop Pa = 65 + 95 = 160

Required profit = 160 × 3 = Rs 480

Hence, option D is correct.

3
The number of pencil sold by Shop La and Shop Na together is approximately how much percentage more than the number of pen sold by Shop La?
» Explain it
D
Pencil sold by Shop La = 70

Pencil sold by Shop Na = 115

Pen sold by Shop La = 105

Required percentage

70 + 115 – 105  × 100
105

80  × 100 = 76.19% ≈ 75%
105

Hence, option D is correct.

4
Find the number of all the items sold by Shop Pa and Shop Na.
» Explain it
B
Total items sold by Shop Pa = 80 + 90 + 95 + 90 + 75 = 430

Total items sold by Shop Na = 110 + 115 + 85 + 80 + 90 = 480

Total items = 430 + 480 = 910

Hence, option B is correct.

Total discount = 75 ×  4  × 5
5

= Rs 300

Hence, option E is correct.
