1.	S. Oftwo numbers, the first nomber is five times the second When 21 is added to each mumber, the first numher becoemstwo times thesecond number. Find the numbers
Answer» let the no.s be x and y ATQ=> x = 5y ......(1) when 21 added to both then => (x+21) = 2(y+21)....(2) now putting the value of x in the 2nd equation=> 5y +21 = 2y+42=> 5y-2y = 42 -21=> 3y = 21=> y = 21/3 = 7 and x = 7*5 = 35.

Answer»

let the no.s be x and y

ATQ=> x = 5y ......(1)

when 21 added to both then

=> (x+21) = 2(y+21)....(2)

now putting the value of x in the 2nd equation=> 5y +21 = 2y+42=> 5y-2y = 42 -21=> 3y = 21=> y = 21/3 = 7

and x = 7*5 = 35.
