I’m having legit troubles in ratios! Specially when to choose option d and when to compare! I asked the same query yesterday but didn’t get satisfying reply! Hopefully , you will clear my confusion.
In Ratios can be tricky - #5 by Tishi there isn’t any “ratios” for us to compare as we know the exact number of apples and mangoes in the basket.
In the problem you showed, it’s a ratio so there could be multiple answers. It does not necessarily mean that the answer is D - you’ll need to check that yourself (by taking extremes for instance).
Okay🤦🏼♀️
