Answer 1

Answer:

D) 23.4 is the right answer

Answer 2

Let us consider Jackie takes X days to complete 65% of the total work,

∴ we can say that :-

$\frac{1}{3}$ : 12 = 65% : X

$\frac{1}{3}$ : 12  = $\frac{65}{100}$ : X

$\frac{1}{3}$ ×$\frac{1}{12}$ =$\frac{65}{100}$ ×$\frac{1}{x}$

$\frac{1}{36}$ =$\frac{65}{100x}$

100 X = 36 × 65

X = 36 × 65 ÷100

X=23.4

Ans :- Jackie takes 23.4 days to complete 65% of total work.
