Answer:
27 rupees, 7000, 2836610, 188, 26
Step-by-step explanation:
Q.18 >
Total profit = 47 rupee
Total loss = (12+8) = 20 rupee
As total profit is more than total loss, there will be a net profit of (47-20) = 27 rupees in 3 days.
Q.19 >
a) 1487×7 -487×7
= 7 (1487-487) >[A×(B-C)]
= 7(1000)
= 7000
b) 28945×99-28945
= 28945 × (100-1) -28945
= 2894500 - 28945 -28945
= 2836610
Q.20 >
a) substract the sum of -1032 and 878 from -34
= 34-(-1032+878)
= 34 - (-154)
= 34 + 154
= 188
b) 45- [38- {60÷3-(6-9÷3)÷3}]
=45- [38- {60÷3-(6-3)÷3}]
=45- [38- {20-3÷3}]
=45- [38- {20-1}]
=45- [38- 19]
=45- 19
=26
