Sugar-------Flour
--13 --------- 18
--10 ---------- x

$$13x = 180$$ ->$$x = \frac{180}{13} = 14$$(approximately)

Therefore, for 10 ounces of sugar, we would have 14 ounces of flour(Option B)

13 ------ 18
10 ------ x

13x = 180
x =180/13 = 13.xx ~ 14 ( as x >13)

(B) imo

IMO B
sugar:flour = 13:18 and only 10 ounces sugar is used than 13x=10
x=10/13 and flour is 18*10/13= 13.8= 14 approx
If you like my explanation please give me Kudos thanks in advance

The ratio of ounces of sugar to flour is
13:18 (given in statement)

So the same ratio to be maintained for the recipe to work
Therefore,
Let the ounce of flour be X
13:18 = 10:X
X= 180/13
= 13.8

Approx 14

Ans is B

Without much calculation we can solve this problem

13:18 , which is nothing but 1:1.4

So flour used should be 140% of sugar. Now if 10 ounce of sugar is used, we need 14 ounce of flour (140% of 10 ounce)

Ans: B
