The line graph shows the Production (in crores) of three companies over years. Find the year in which total production in company Z is 30 percent more than that of company X.

2020

Solving one by one for each option ,

1. 2021

Production of Z = 70

Production of X =86

Production of Z is less than Production of X . So not satisfy

2. 2019

Production of Z = 45

Production of X = 57

Production of Z is less than Production of X . So not satisfy

3. 2020

Production of Z = 65

Production of X = 50

Required percentage = \(\frac{65 - 50}{50}\) × 100 = 30%

So , Production of Z is 30% more than production of X.

4. 2018

Production of Z = 65

Production of X = 45

Required percentage = \(\frac{65 - 45}{45}\) × 100 = 44.44%

So , Ans :-  2020
