Option 1: 6%
Option 2: 16%

Solution :
Total workers = 50
Number of workers earning Rs. 140 = 26
Number of workers earning Rs. 160 = 34
So, the number of workers earning between Rs. 140 and Rs. 160 = 34 – 26 = 8
$\therefore$ Percentage of the factory workers earn between Rs. 140 and Rs. 160 = $\frac{8}{50}\times100$ = 16%
