Solution

Explanation for part a): $40 %$
Step 1: Find the equivalent percentage value to be increased.
$\Rightarrow 40 % o f R s . 130 \Rightarrow \frac{40}{100} \times 130 = \frac{40 \times 130}{100} = 52$
Thus, $R s . 52$ is to be added.
Step 2: Find the increased value.
$\Rightarrow R s . 130 + R s . 52 = R s . 182$
Hence, $R s . 130$ increased by $40 %$ will be equal to $R s . 182$ .

Explanation for part b): $10 %$
Step 1: Find the equivalent percentage value to be increased.
$\Rightarrow 10 % o f R s . 130 \Rightarrow \frac{10}{100} \times 130 = \frac{10 \times 130}{100} = 13$
Thus, $R s . 13$ is to be added.
Step 2: Find the increased value.
$\Rightarrow R s . 130 + R s . 13 = R s . 143$
Hence, $R s . 130$ increased by $10 %$ will be equal to $R s . 143$ .

Explanation for part c): $8 %$
Step 1: Find the equivalent percentage value to be increased.
$\Rightarrow 8 % o f R s . 130 \Rightarrow \frac{8}{100} \times 130 = \frac{8 \times 130}{100} = \frac{104}{10} = 10.40$
Thus, $R s . 10.40$ is to be added.
Step 2: Find the increased value.
$\Rightarrow R s . 130 + R s . 10.40 = R s . 140.40$
Hence, $R s . 130$ increased by $8 %$ will be equal to $R s . 140.40$ .

Explanation for part d): $150 %$
Step 1: Find the equivalent percentage value to be increased.
$\Rightarrow 150 % o f R s . 130 \Rightarrow \frac{150}{100} \times 130 = \frac{150 \times 130}{100} = 195$
Thus, $R s . 195$ is to be added.
Step 2: Find the increased value.
$\Rightarrow R s . 130 + R s . 195 = R s . 325$
Hence, $R s . 130$ increased by $150 %$ will be equal to $R s . 325$ .
