Question
Speed of a car and a bus is 20 km/h and 12 km/h,
respectively. If the time taken by the car to cover a distance of ‘8x’ km is 1 hour less than time taken by the bus to cover a distance of ‘6x’ km, then find the value of ‘8x’Solution
According to the question, (6x/12) – (8x/20) = 1 Or, (6x × 5 – 8x × 3) ÷ 60 = 1 Or, (30x – 24x) ÷ 60 = 1 So, x = 10 Required value = 8 × 10 = 80
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
111.89 × 4.12 – 504.04 ÷ 2.12 = 170.12 + ?
66.05 × 17.95 – 38.99 × 18.12 = (60 + ?) × 6
Find the approximate value of Question mark(?) for given equation.Â
135.86% of 249.99 + 24.95 × 14.03 ÷ 2.01 = ?
386.99 + 397.99 + ? - 232.02 = 35.02 × 31.99
( 22.01%  of 899.80 ) × 15.99 = ? 2 + 27.98 × 2400 ÷ 800
44.89% of 1199.78 + 319.68 = ? × 42.79
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
?% of [(12.96 × 40.05) + 25.08 × 18.96] = 17.96 × 22.05 + 3.05 × 66.96Â
