Question

The greatest number that will divide 145 175 160 leaving remainder 10 in each case

Answer 1

Answer:

15

Step-by-step explanation:

Since the remainder is 10, the divisor must be greater than 10- 11, 12, 13, 14 etc.

Let the number be x

145= x*a+ 10

x*a= 135

175= x*b+ 10

x*b= 165

160= x*c+ 10

x*c= 150

The HCF of 135, 175 and 150 will lead to the number x

HCF= 15

Therefore the number is 15
