Question
M and N started a business by investing Rs.5500 and
Rs.6500 respectively. After 6 months, M and N increased their investments by 40% and Rs.2400 respectively. The annual profit share of N was Rs.2100. Find the total annual profit received by them together.Solution
Increased investment of M = 5500 x 1.4 = Rs.7700 Increased investment of N = 6500 + 2400 = Rs.8900 Ratio of profit share of M and N = (5500 x 6 + 7700 x 6) : (6500 x 6 + 8900 x 6) = 6:7 So, total annual profit received by them together = 2100 x (13/7) = Rs.3900

The least number which when divided by 5, 15 and 25 leave a same remainder 2 in each case?Â
LCM of two numbers is 10 times their HCF. The product of the numbers is 18000. What will be the maximum possible difference between the numbers?
Find the LCM of 20, 30, 40, 50.
Two numbers are in the ratio 2:7. The product of their H.C.F. and L.C.M. is 5054. The sum of the numbers is:
Let N be the greatest number that will divide 85, 112, 139 leaving the same remainder in each case. Then sum of the digits in N is:
Three numbers are in the ratio 3:7:2 respectively. If the HCF of the numbers is 5, then find the LCM of the numbers.
The smallest number which when divided by 27 and 36 leaves remainder 12 and 21 respectively is:
