OA is D.
OG10 DS problem # 24

BTW I would like to point out that in OG10 the problem has condition #2 as

s-r=75/100

While the answer explanation has it as

s+r=75/100

either way I dont understand how they arrived at ans .D

To solve this entire mystery..

Saw the OG 10 - Q 24

its

1. R = 3/4 *S

2. R :- S = 75/100

and yes its "D" if thats the case!!!!
