Step-by-step explanation:
11. No. of steps taken in north = 15
No. of steps taken in south = 30
Total no. of steps = 30 + 15 = 45
Length of each step = 30 cm
Total distance covered by Kaveri = 45 × 30 cm
= 1350 cm
So, Total distance covered by the Kaveri is 1350 cm.
12. Amount in her bank before depositing = 25,500 Rs
Amount deposited in the bank = 10,700 Rs
Amount in her bank after depositing = 25,500 + 10,700 = 36,200 Rs
Amount withdrew from the bank = 1/2 of whole = 1/2 × 36,200 Rs = 18,100 Rs
Total amount in the bank now = (36,200 - 18,100) Rs = 18,100 Rs
So, amount in the bank now is 18,100 Rs.
13. Earning of her on daily wages = 2,500 Rs
Savings of her on daily wages = 485 Rs
Earning of her in a month = 2,500 Rs × 30 = 75,000 Rs
Savings of her in a month = 485 Rs × 30 = 14,550 Rs
Amount which is spent in a month = 75,000 Rs - 14,500 Rs = 60,450 Rs
So, she spend 60,450 Rs in a month.
14. let the number of attempts needed = x
length of the tree from the ground = 6 feet
length of the jump in one attempt = 2 feet
length of sliping in one attempt = 1 feet
No. of attempts needed to reach at the tree =
=
=
=
So, The monkey need to do 6 attempts to pluck the bananas.
15. Temperature at the frozen seed are kept = -4°C
Temperature needed to be raised to make it soft seed = 20°C
Temperature at the seed become soft = -4°C + 20°C = 16°C
So, 16°C is needed temperature to make seed soft.
16. First combination could be 8957×4×7 = 250796.
Second combination could be 125398×62699×62699 = 250796.
Third combination could be 62699×2×2 = 250796.
