Answers
Answers:
Step-by-step explanation:
Ans 7) Greatest : 98621
Smallest : 12689
Ans 8) Worth of the books sold in the first week of march = Rs. 8,85,921
Worth of the books sold in the first week of march = Rs. 14,76,80
Worth of the books sold in the two weeks of march together
= Rs. 8,85,921 + Rs. 14,76,804
= Rs. 23,62,725
Ans 9) Amount of money the merchant had = Rs. 9,07,640
Number of air conditioners ordered by the merchant = 48
Cost of one air conditioner = Rs. 16,000
∴ Total cost of 48 air conditioners = 48 × Rs. 16,000
= Rs. 7,68,000
∴ Money left with the merchant after the purchase
= Rs. 9,07,640 - Rs.7,68,000
= Rs. 1,39,640
Ans 10) Incorrect product found by the student = 5,342 × 87
= 4,64,754
Correct product = 5,342 × 78
= 4,16,676
Difference between the two products = 4,64,754 - 4,16,676
= 48,078
Ans 11) Distance between Rajeev's house and his office = 21.375 Km
Distance between Rajeev's house and his office and back to his
house = 42.75 Km
∴ Distance covered by Rajeev in 6 days = 6 × 42.75 Km
= 256.5 Km
Ans 12) Cloth needed to stitch a skirt = 2.1 m
Total cloth available = 35.35 m
∴ Number of skirts that can be stitched = 35.35/2.1
= 16.8333
∴ 16 skirts can be stitched.
Ans 13) Population of the city = 3,52,96,405
No. of males in the city = 1,88,59,695
∴ No. of females in the city = 3,52,96,405 - 1,88,59,695
= 1,64,36,710
Ans 14) Number of garments produced in a single day = 3,855
∴ Number of garments produced in 365 days = 365 × 3,855
= 14,07,075
Ans 15) Distance covered by the aeroplane= 850 Km
Time taken by the aeroplane = 1 hour
∴ Speed of the aeroplane = 850 Km/hr
Time given = 73 hr
Speed = 850 Km/hr
∴ Distance covered = Speed × Time
= 850 × 73
= 62,050 Km
Ans 16) Cost of 45 flats = Rs.20,59,46,190
∴ Cost of 1 flat = Rs.20,59,46,190/45
= Rs.45,76,582
Ans 17) Number of dresses to be stitched = 24 dresses
Length of cloth needed to stitch 24 dresses = 66 m
∴ Length of cloth needed to stitch 1 dress = 66 m/24
= 2.75 m
Ans 18) Number of packets = 32
Weight of the 32 packets = 50.4 Kg
∴ Weight of 1 packet = 50.4 Kg/32
= 1.575 Kg
Hope this helps you a lot mate :)
