In finding the HCF of two numbers by division method, the quotients are 1, 8 and 2 respectively, and the last divisor is 105. What is the sum of the numbers?
Answer & explanation
Correct answer: option 2
The two numbers are a and b
c = 105 × 2 = 210
b = 210 × 8 + 105 = 1785
a = 1785 × 1 + 210 = 1995
a + b = 1785 + 1995 = 3780
