Question

If $25\%$ of the number of televisions manufactured by company A over all the years together were black and white, then what was the number of coloured televisions manufactured by company A over the years together?

• A. 1.4 lakhs
• B. 14000
• C. 1.8 lakhs
• D. 18000
• E. 1.5 lakhs

Answer 1

The correct option is C 1.8 lakhs

Total number of televisions manufactured by company A.

= (30 + 35 + 35 + 40 + 45 + 55) thousand
