if r and s are positive integers ,each greater than 1, and if 11(s-1)=13(r-1) what is the least possible value of r+s ?
a]2
b]11
c]22
d]24
e]26
a]2
b]11
c]22
d]24
e]26
If 11 * x = 13 * y, since 11 and 13 are prime numbers, we have x = 13 and y =11
In the problem here. s-1 =13 and r-1 = 11.
s=14, r=12. Ans 26.
