Q1: Renu purchases two bags of fertiliser of weights 75 kg and 69 kg. Find the maximum value of weight which can measure the weight of the fertiliser exact number of times.

Answer: 
 The maximum weight  = HCF of 75 and 69.
 Factors of 75   = 3 ✕ 5 ✕ 5
 Factors of 69   = 3 ✕ 69
    HCF  = 3
 ∴ the required weight is 3 kg.

Rules of Divisibility

Rules of Divisibility
 
2: A number is divisible by 2 if the last digit (unit's digit) is even. e.g. 32, 459992

3: A number is divisible by 3, if the sum of digits of a number is divisible by 3.
    e.g. 252 = 2 + 5 + 2 = 9 ÷ 3 = 3 ∴ 252 is divisible by 3

4: A number is divisible by 4, if the last two digits of the number is divisible by 4.
    e.g. 81924 = since last two digits 24 is divisible by 4, hence the number.

5: A number is divisible by 5, if the last digit of the number is 0 or 5.
    e.g. 35, 200, 1005

6: A number is divisible by 6, if the number is divisible by both 2 and 3.
