Question
‘A’ and ‘B’ started
moving towards each other at same time with a speed of 20 km/hr and 15 km/hr, respectively. If the distance covered by ‘A’ is 25 km more than that by ‘B’, when they meet then find the initial distance between them.Solution
The LCM of two numbers is 216 and their HCF is 36. If one of the numbers is 72, the other number is:
Find the largest number of the five digit which is exactly divisible by 48, 72 and 108.
...The LCM of two numbers is 840 and their HCF is 14. If one of the numbers is 84, find the other number.
A boy can swim in still water at a speed of 8 km/hr. If the speed of the current would have been 3 km/hr, then the boy could swim 55 km
The ratio of two numbers is 10:12 and their LCM is 240. The numbers are:
Three numbers are in the ratio 7:5:4 respectively. If the HCF of the numbers is 3, then find the LCM of the numbers.
A number is three times another number and their HCF is 8. What is the sum of the squares of the numbers?
The LCM of two numbers is 2250 while their HCF is 50. If one of the numbers is 450, then the other number is:
The greatest number by which if 1468 and 2258 are divided the remainders will be 8 and 6 respectively, is:
Let N be the greatest number that will divide 72, 105, 138 leaving the same remainder in each case. Then sum of the digits in N is:
