Question 1.
The number of people who visited during common wealth games in New Delhi for the first four days was re-corded as 15,290, 14,181, 14,235 and 10,578. Find the total number of people visited in these four days ?
Answer:
Number of people visited common wealth games on the first day = 15,290

Question 8.
The cloth required to make a shirt of school uniform for each boy is 1 m 80 cm. How many shirts can tailor stitch using 40 m. of cloth ? How much cloth will be left ?
Answer:
The cloth to be stitched = 40 m = 40 × 100 cm
(∵ 1 metre = 100 cm)
= 4000 cm
The cloth required for one shirt
= 1 m 80 cm
= 180 cm (∵ 1 metre =100 cms)
Number of shirts can be stitched = \(\frac{4000}{180}\)
= 22\(\frac{2}{9}\)
The tailor can stitch 22 shirts.
The cloth will be left = \(\frac{2}{9}\) × 180
= 40 cm
