Answers
Given:
Renmark decided to sell fruits for his weekly allowance.
Mango sold 40 per kilo and banana are sold 20 per kilo.
To find:
What is the least number of fruit trays he makes so there is an equal number of mango and banana in each tray?
Solution:
To find the least no. of fruit trays Renmark made so that there is an equal no. of mango and banana in each tray, we will calculate the Least Common Multiple(i.e., L.C.M.) of 40 and 20.
We will use the prime factorisation method to calculate the L.C.M. of 40 and 20:
Factors:
20 = 2 × 2 × 5
40 = 2 × 2 × 2 × 5
L.C.M.:
∴ L.C.M. of 20 & 40 = 2 × 2 × 2 × 5 = 40
Thus, the least number of fruit trays Renmark makes so that there is an equal number of mango and banana in each tray is → 40.
