Solution:
We have given the total number of apples = 527.The total number of pears = 646.
The total number of oranges = 748.
Therefore, the total number of heaps to be formed is given by HCF of 527, 646, and 748.
Finding the prime factorization of 527, 646, and 748:
Therefore, the HCF of 527, 646, and 748 = 17.
Hence, the total number of heaps formed is 17.
The number of apples in each heap is,
The number of pears in each heap is,
The number of oranges in each heap is,
Therefore, the total numbers of apples, pears, and oranges possible in each heap are respectively 31, 38, and 44.
Hence option (1) is correct.
