Question
The average of two consecutive even numbers is 73. If
the smaller number is increased by 40% and the larger number is decreased by 40%, then find the difference between the numbers obtaineSolution
Let the two consecutive even numbers be x and x + 2.
ATQ,
x + 1 = 73 => x = 72
Required difference = 1.4 × 72 - 0.6 × 74 = 100.8 - 44.4 = 56.4
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exactvalue.)
20% of 80 × 26% of 65 = ?
(20.98 ÷ 2.91) + (15.12 – 5.96) = ?
( 19.95% of 799.89 ) × 12.05 = ? 2 + 18.99 × 6250 ÷ 1250
35.05% of 14.87 × (13.02 – ?) + 30.19 = 188.7
