As the other two are related to B, let us take B as 100...
So A is 40% greater, meaning A is 100+40% of 100=100+40=140
Now B is 30% less than C, so 100=C-30% of C=70 % of C...C=100*100/70=1000/7=143
So A is 140 and C is 143...
Therefore, A is 100*140/143=~98%

I took C as being 100, which will then make B = 70 and then A = 98

It was easier for me to do 10% of 70 = 7 then, 7 x 4 to get 40% which equals 28. then 70 + 28 = 98

I took C as my starting point just as you did

C=x
B=0.7x
A=0.7x+(0.4X0.7)x
A=.98x


98%

The answer is D

same approach just a different look.

Let the sales of business C be 100

Then sales of business B which is 30% less becomes 70.

Sales of business A is 40% greater than B. Therefore, \(\frac{140}{100}\) * 70 = 98

Business A is 98% of Business C.
