= 1094 +1812+2050 +2751

Now,

∴ Total number of tickets sold on four days is 7707.

Votes registered by the nearest rival = 348700

Margin by which the successful candidate won= 577500 – 348700

Now,

∴The margin by which the successful candidate won is 228800.

**Question 4.**

Kirti bookstore sold books worth ₹ 2,85,891 in the first week of June and books worth ₹ 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:**

Price of books sold in the first week = ₹ 285891 .

Price of books sold in the second week = ₹ 400768

Price of books sold in two weeks = ₹ 285891 + ₹ 400768

Now,

∴ Sale in two weeks is of ₹ 686659

Since 400768 > 285891

∴ Sale in the second week is greater.

Difference in the sales amount = ₹ 400768 – ₹ 285891

Now,

∴ Sale in the second week is more by ₹ 114877.

Now,

∴Number of screws manufactured in the month of January 2006 = 87575.

Cost of 1 radio set = ₹ 1200

Cost of 40 radio sets = ₹ (1200 x 40)

Now,

∴ Cost of 40 radio sets = ₹ 48000

∴Money left with the merchant after purchase of radio sets

Now,

∴ Money left after the purchase = ₹ 30592

**Question 8.**

**Question 9.**

To stitch a shirt, 2 in 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how much cloth will

remain?

**Solution:**

Total cloth = 40 m = 40 x 100 cm

= 4000 cm

Cloth needed for 1 shirt = 2 m 15 cm

= 2 x 100 cm + 15 cm = 215 cm

Number of shirts stitched out of total cloth = 4000 ÷ 215

Now,

∴ 18 shirts can be stitched and cloth left over is 130 cm i.e., 1 m 30 cm.

**Question 10.**

**Solution:**

Van can carry a weight of 800 kg i.e., 800000 g

Weight of one packet = 4 kg 500 g = 4500 g

Number of packets that can be loaded in the van = 800000 + 4500

The distance between the school and the house of a student is 1 km 875 m. Everyday she walks both ways. Find the total distance covered by her in six days.

Distance walked by the student both ways between school and home

= 1 km 875m x 2

Now,

∴ Distance walked in 1 day = 3 km 750 m

Distance walked in 6 days = 3 km 750 m x 6

Now,

∴ Distance walked in 6 days = 22km 500 m.

**Question 12.**

A vessel has 4 litres and 500 ml of curd. In how-many glasses, each of 25 ml capacity, can it be filled?
