Question
John has finished planting 1/4 th of the area
of rectangular garden which is 12ft wide. When he finishes planting another 90 sq. ft of the garden, he would have finished 2/5th of the area. What is the length of the garden?Solution
Let the area of the garden be ‘x’ sq. ft, then the difference between 2/5 and 1/4 of the area is 90 sq. ft, ⇒ (2/5- 1/4) × x = 96 ⇒ 3/20 x = 90 sq. ft ⇒ x = (90 × 20)/3 = 600 ∴ Length = Area/Width = 600/12 = 50 ft.
(1/2) – (3/5) + 3(1/3) = ? + (5/6)
9 × 40 × 242 × 182 = ?2
212.3 × 4414.7 × 4623.4 × 4845.85 = 462?
52% of 400 + √(?) = 60% of 600 - 25% of 400
447.8 × 441.2 ÷ 445 = 44 × 44?
Determine the value of 'p' in following expression:
720 ÷ 9 + 640 ÷ 16 - p = √121 X 5 + 6²- 7What will come in the place of question mark (?) in the given expression?
(? ÷ 16) = (20 ÷ ?) X 20- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 - What will come in place of the question mark (?) in the following questions?
25% of 360+40=? 30% of 2200 +’?’ x 50 – 1020 = 11x 306 + (√ 2250 ÷ 0.1) Â
