abcd as 1:2::2:4

Sir, what if, we assume a=1, b=2, & c=4 then proportionality is satisfied and hence the first option becomes correct.

these questions are enough for NMAT and snap but do follow a few other books as he has not covered everything in ratio and proportion.

better use 1,2,3,6. cz when the value of b is same then the nos. in proportion would be a,b,c and mean value would be b^2 = ac. so all the calculations would change. hence when we are having 4 variables - a,b,c,d then we must use 4 different values.
