(iv) A company with 30 employees decided to distribute ₹ 90,000 as a special bonus equally among its employees. Draw tree diagram to show how much will each receive?

Answer 1

(i) People who visited the library for the past 5 months = 1210 + 2100 + 2550 + 3160 + 3310 = 12,330

Total number of people visited = 12,330

(ii) Total bank deposit of Ram = ₹ 7,55,250

(iii) Number of bicycles manufactured in a day = 1600

Number of bicycles manufactured in 20 days = 1600 × 20 = 32,000

Number of bicycles manufactured in 20 days = 32,000
