Tickets sold on 2^{nd} day = 1812

Tickets sold on 3^{rd} day = 2050

Tickets sold on 4^{th} day = 2751

Total tickets sold = 1094 + 1812 + 2050 + 2751 = 7,707

Margin = 2,28,800.

Question 4.

Kirti bookstore sold books worth Rs2,85,891 in the first week of june and books worth Rs 4,00,768 in the second week of the month. How much was the sale for the two weeks together? In which week was the sale greater and by how much?

Solution:

Value of Books sold in 1^{st} week = Rs 2,85,891

Value of books sold in 2^{nd} week = Rs 4,00,768

Total sale = sale in 1^{st} week + sale in 2^{nd} week

= 2,85,891 + 4,00,768 = 6,86,659

The sale for the two weeks together was 6,86,659

Since 4,00,768 > 2,85,891, sale in 2^{nd} week was greater than 1^{st} week.

400768 – 285891 = 114877

The sale in 2^{nd} week was larger than the sale in 1^{st} week Rs 1,14,877

Question 9.

To stitch a shirt, 2 ml5 cm cloth is needed, out of 40 m cloth, how many shirts can be stitched and how much cloth will remain?

(Hint: convert data in cm.)

Solution:

2m 15cm = 215 cm( 1 m = 100 cm)

40m = 40 × 100

= 4000 cm

cloth required for one shirt = 215 cm

Number of shirt that can be stitched out of 4000 cm = 4000 ÷ 215

therefore, is shirts can be made 130 cm, i,e, 1 m 30 cm, cloth will remain.

Question 10.

Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg?

Solution:

1 kg = 1000 g

4 kg 500 g = 4500 g

800 kg = 80 × 1000 = 800000 g

Number of boxes that can loaded in the van = 800000 ÷ 4500 = 800 ÷ 4.5

Hence, 117 boxes at maximum can be loaded in the van
