Question 1.
Solve the following word problems.
(a) A soap factory produced 26,92,645 soap cakes in one year. In the next year, it produced 8,67,205 soap cakes more. How many soap cakes did the factory produce in the second year?
Solution:
To find out the total number of soap cakes produced in the second year, we have to add production in one year and the next year.
Soap cakes in one year = 2692645
Extra soap cakes in next year = +867205
Total produce in second year= 3559850
35,59,850 soap cakes were produced in the second year.

(b) In one year, Mr Mohan earned ₹ 5,57,088, his wife earned ₹ 3,23,672 and their son earned ₹ 2,96,750. How much money did Mr Mohan’s family earn in one year?
Solution:
We have to add the earnings of family members.
Mr Mohan earned money = 557088
His wife earned money = +323672
Their son earned money = +296750
Total earning = 1177510
Mr Mohan’s family earns ₹ 11,77,510 in one year. (c) In an examination conducted by an educational organisation. 15,83,693 candidates appeared. Out of these 7,49,865 passed. How many candidates failed the examination?
Solution:
If we subtract passed candidates from appeared candidates then we get failed candidates.
Total candidates who appeared in the examination = 1583693
Passed candidates = -749865
Failed candidates = 833828
8,33,828 candidates failed in examination.

(d) In an election, the winning candidate got 6,28,496 votes and his rival got 4,56,298 votes. If 3,846 votes were declared invalid, what was the total number of votes polled?
Solution:
No. of votes winning candidates got = 628496
No. of votes rival got = +456298
No. of votes declared invalid = +3846
Total number of votes polled are 10,88,640. (e) Find the sum of the greatest 8-digit, 7-digit, and 6-digit numbers.
Solution:

Greatest 7-digit number = +9999999
Greatest 6-digit number = +999999
Sum = 110999997
The sum of the greatest 8-digit, 7-digit, and 6-digit numbers is 11,09,99,997.
