Orange : water 4x : x Total = 5 x 75 litre of mixture taken out, Orange = 4x/5x × 75 = 60 Orange in mixture = 4x – 60 Water in mixture = x/5x × 75 = 15 Water = (x – 15) + 25 = x + 10 According to the question, (x+10)/(4x-60) = 40/60 6x + 60 = 16x – 240 10x = 300 ∴ x = 30 Initial quantity of mixture = 4x + x = 5x Initial quantity of mixture = 5 × 30 = 150 litres
(12% of 1250 + 85% of 400) x 10 = ?2
What will come in the place of question mark (?) in the given expression?
(70 × 8 ÷ 10) × 5 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
236.23 - 653.23 + 696.23 = ?
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2
808 ÷ (128)1/7 + 482 = 4 × ? + 846
30% of 215 + 135% of ? = 469.5
