Match the ratios on the left hand side with their respective values of 1 unit.

• A. 1 unit = 6
• B. 1 unit = 9
• C. 1 unit = 15
• D. 1 unit = 13

Answer 1

We can solve this using unitary method.

(i) Value of 5 units = 65
$\Rightarrow$ Value of 1 unit = $\frac{65}{5}=13$

(ii) Value of 4 units = 60
$\Rightarrow$ Value of 1 unit = $\frac{60}{4}=15$

(iii) ​​​​​​​Value of 7 units = 42
$\Rightarrow$ Value of 1 unit = $\frac{42}{7}=6$
​​​​​​​
​​​​​​​(iv) Value of 6 units = 54
$\Rightarrow$ Value of 1 unit = $\frac{54}{6}=9$
