Question

Mark (✓) against the correct answer
45 cows can graze a field in 12 days. How many cows will graze the same field in 9 days?

(a) 60 days
(b) $38\frac{3}{4}$ days
(c) 54 days
(d) none of these

Answer 1

Number of cows that graze the field in 12 days = 45

Number of cows that graze the field in 1 day = $45\times 12$

∴ Number of cows that graze the field in 9 days = $\frac{45\times 12}{9}$ = 60
