Directions: Read the line graph carefully and answer the following que...
For P in 2019,
Income = Rs. 40000
Expenditure = 40000 × 4/5 = Rs. 32000
⇒ Savings = 40000 – 32000 = Rs. 8000
For P in 2020,
Income = Rs. 50000
Expenditure = 50000 × 3/5 = Rs. 30000
⇒ Saving of P in 2020 = 50000 – 30000 = Rs. 20000
Similarly, we can find the expenditure and saving of Q, R, S, and T in two years
Saving of P in 2019 is Rs. 8000 and saving of P in 2020 is Rs. 20000
⇒ Required percentage = (20000 – 8000)/8000 × 100 = 150%
Saving of Q in 2019 is Rs. 10000 and saving of Q in 2020 is Rs. 10000
⇒ Required percentage = (10000 – 10000)/10000 × 100 = 0%
Saving of R in 2019 is Rs. 12500 and saving of R in 2020 is Rs. 12000
⇒ Required percentage = (12500 – 12000)/12000 × 100 = 4.17% decreases
Saving of S in 2019 is Rs. 10000 and saving of S in 2020 is Rs. 10000
⇒ Required percentage = (10000 – 10000)/10000 × 100 = 0%
Saving of T in 2019 is Rs. 12000 and saving of T in 2020 is Rs. 15000
⇒ Required percentage = (15000 – 12000)/12000) × 100 = 25%
∴ P has the highest percentage increase in saving.
