You can put this solution on YOUR website! 1. If ram is 10 years younger the his brother shyam and after 7 years ram's age will be half of shaym's age. find actual age of ram and shyam.
shyam age =x
Ram = x-10
After 7 years
Ram age = x-10+7 = x-3
shyam age = x+7
1/2(x+7)= (x-3)
x+7 = 2(x-3)
x+7=2x-6
x=13
you find out Ram's age
2. mat and prateek started a business with initial contribution of 1000 and 1250
respectively, after a year profit earned is is Rs.100/-. what is the profit of mat and prateek.
The ratio of their investment = 1000/1250 = 4/5
so profit is shared in that ratio
3. If worker finishes a wall construction in 10 days and 2nd worker in 7 days, how many days it will take to finish if both of them work together.
they will do 1/10 + 1/7 = 17/70 of the job in 1 day
so they will take 70 /17 days together.
