What approximate value will come in place of the question mark (?) in the given questions? (You are not expected to calculate the exact value.)

Question 74

45% of 401 ÷ 3 - ? = 6.022

Solution

Expression : 45% of 401 ÷ 3 - ? = 6.022

=> $$45 \%$$ of $$400 \div 3 - x = 6$$

=> $$\frac{45}{100} \times 400 \div 3 = 6 + x$$

=> $$\frac{45 \times 4}{3} = 6 + x$$

=> $$x + 6 = 15 \times 4 = 60$$

=> $$x = 60 - 6 = 54$$
