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.

Weight of the two bags = 75 kg and 69 kg

Maximum weight = HCF (75, 69)

75 = 3 × 5 × 5

69 = 3 × 23

HCF = 3

Therefore, the maximum value of weight, which can measure the weight of the fertilizer exact number of time, is 3 kg.
