Question
In a colony, there are 100 APL families and 50 BPL
families. Each APL and BPL family got blankets equal to 20% and 68%, respectively of total number of families (APL + BPL) in the colony. Find the difference between total number of blankets received by APL and BPL families.Solution
Total number of families in the colony = 100 + 50 = 150 Number of blankets received by APL families = 100 x 0.20 x 150 = 3000 Number of blankets received by BPL families = 50 x 0.68 x 150 = 5100 Required difference = 5100 - 3000 = 2100
The LCM of two numbers is 5 times of their HCF. The sum of LCM and HCF is 300. If one of the number is 250, then the other number is:
If total number of factors of 2,520 is 'y', then find the value of (y - 4)(y + 6).
Find the greatest number that will divide 115, 149 and 183 leaving remainders 3, 5, 7 respectively.
Find the least common multiple of (16/20), (8/10), and (4/5).
The least number which when divided by 9, 12, 15, 18, and 21 leaves the same remainder 7 in each case, is:
The HCF of two numbers is 6 and their LCM is 84. If one of these numbers is 42, then the second number is:
- The L.C.M and H.C.F of two numbers have a sum and difference of 440 and 120. If one number is 40, find the other.
Find the HCF and LCM of 18 and 30.
The LCM of two numbers is 15 times their HCF. The sum of HCF and LCM of these numbers is 352.If one of the numbers is 110, find the other number.
