My approach is:
1) The ratio of a to b is 6 to 7 means a/b = 6/7
2) After cross-multiplying, 7a=6b
3) Based on 7a=6b, let's use a common symbol to make calculation simplier, a=6β and b=7β
4) for this question we converted a and b into β (a=6β and b=7β)
5)Let's look to options.
Choice A) a=36,b=49 in other words 6β=36 and 7β=49 if we assume that β is 6 it is true for 36 BUT wrong for 49 so this option is wrong.
6) Use this method other options than you will see only B and E are true.
