Question

Find the percentage change from the first quantity to (1) ₹80,₹120 (ii) 75 kg, 60 kg ​

Answer 1

Answer:

Solution:

(i) Rs. 80, Rs. 120

Increase = 120 - 80 = Rs. 40

Percentage of increase = \frac{40}{80}\times100=50\%

Hence, increase = 50%

(ii) 75 kg, 60kg

Decrease = 75 - 60 = 15 kg

Percentage decrease = \frac{15}{75}\times100=20\%

Hence, decrease = 20%

(iii) 50cm ,45 cm

Decrease = 50 - 45 = 5 cm

Percentage decrease = \frac{5}{50}\times100=10\%

Hence, decrease = 10%
