Answers
Answer:
5. Greatest 5-digit number is 76432 and Least 5-digit number is 23467. Their difference is 52965.
6. 1 day = 2825 screws
31 days = 2825 * 31 screws
= 87575 screws.
7. 1 radio set = rs 1200
40 radio sets = rs 1200 * 40
= rs 48,000
Money she had = rs 78,592
Money left with her after buying 40 radio sets
= rs ( 78,592 - 48,000)
= rs 30,592
8. 7236 * 65 = 470340
7236 * 56 = 405216
The difference is = 65125
9. 2m 15cm = 1 shirt
215 cm = 1 shirt
1 cm = 1/215 shirt
40 m = 4000cm = 4000/215 shirts
= 18 shirts (approx.)
10. 4kg 500g = 1 box
4.5kg = 1 box
1 kg = 1/4.5 box
800 kg = 800/4.5 boxes
= 177 boxes(approx.)
11. Distance = 1km 875m = 1.875km
In 1 day she covers twice the distance;
so, the distance covered in 1 day = 1.875 * 2 km
1 day = 3.75 km
6 days = 3.75 * 6 = 22.5 kms
12. Total curd = 4l 500ml = 900ml
Total glasses = 900/25
= 36 glasses
I hope my answer was a help to you. :)
