Question 1: 64% of a bigger number is 6 more than 75% of a smaller number. The bigger number is 140 more than, the smaller one. What is the sum of both numbers?
Answer: 1660
Explanation: Let the smaller number be x, then
The bigger number = (x + 140)
According to the question
(x + 140) × 64% – x × 75% = 6
0.64x + 89.6 – 0.75x = 6
⇒ x = 760
Required sum = Smaller number + Bigger number = x + (x + 140) = 760 + 900 = 1660

Increased length = 100 x 116/100 = 116 units
Decreased breadth = 40 x 75/100 = 30 units
Area decreased by = (100 x 40) - (116 x 30) = 520 sq units
Required percentage ={520/(100 x 40)} x 100% = 13%
