Step-by-step explanation:
Solution:
a)
Given,
Total amount = 15000
Let the amount given to Ram and Karthik be 4x and 11x.
Then,
Total amount = 4x+11x = 15x.
So,
15x = 15000
x = 1000
So Ram has 4x= 4000 Rs and Karthik has 11x= 11000 Rs.
b)
Given,
Total amount= 34000
Let Shobha, Uma and Roshan have 8y, 2y and 7y Rs respectively.
Total=8y+2y+7y = 17y
So,
17y = 34000
y = 2000 Rs.
So shobha has 8y= 16000 Rs, Uma has 2y=4000 Rs and Roshan has 7y= 14000 Rs.
