1.	hediferenceofthetwogreateGiven three numbenumbers is added fo the smallest bumber to obtainnew number. The average of the new number and thetwo greater numbers is 10 more than the average of th9.given three numbers. What number is added to thesmallest number?
Answer» Let three numbers are x, y, zLet y, z is greater numbers and x is smallest numberLet New number is n Then,(y - z) + x = n.... (1)(n + y + z)/3 = 10 + (x + y + z)/3n = 30 + x.....(2) Put value of n from eq(2) in eq(1) We get,(y - z) + x = 30 + xy - z = 30 Therefore number added to smallest number is 30

Answer»

Let three numbers are x, y, zLet y, z is greater numbers and x is smallest numberLet New number is n

Then,(y - z) + x = n.... (1)(n + y + z)/3 = 10 + (x + y + z)/3n = 30 + x.....(2)

Put value of n from eq(2) in eq(1)

We get,(y - z) + x = 30 + xy - z = 30

Therefore number added to smallest number is 30
