Answers

Given,
Ram and Shyam together have Rs. 400.
If Rs. 125 is given to each of them, then the ratio of their amounts will become = 15:11
To find,
The difference in their amounts.
Solution,
We can simply solve this mathematical problem using the following process:
Let us assume that Ram and Shyam have Rs. x and Rs. y, respectively.
Now, according to the question;
Ram and Shyam together have Rs. 400
=> Rs. x + Rs. y = Rs. 400
=> x+y = 400
=> y = 400-x
{Equation-1}
Now, according to the question;
When Rs. 125 is given to each of them,
Final amount with Ram = Rs. (x+125)
Final amount with Shyam = Rs. (y+125)
Now,
After Rs. 125 is given to each of them, the ratio of their amounts will become = 15:11
=> (Final amount with Ram)/(final amount with Shyam) = 15/11
=> (x+125)/(y+125)=15/11
=> 11(x+125) = 15(y+125)
=> 11x + 1375 = 15y + 1875
=> 11x = 15y + 500
=> 11x = 15(400-x) + 500
{according to equation-1}
=> 11x = 6000 - 15x + 500
=> 26x = 6500
=> x = 6500/26
=> x = 250
=> Initial amount of money with Ram = Rs. 250
Now, substituting the value of x in equation-1, we get;
y = 400-x = 400-250 = 150
=> y = 150
=> Initial amount of money with Shyam = Rs. 150
Now,
The difference in their amounts
= (initial amount of money with Ram) - (initial amount of money with Shyam)
= Rs. 250 - Rs. 150
= Rs. 100
Hence, the difference in the amounts with Ram and Shyam is equal to Rs. 100.
