Let, number of book and number of pen sold by shopkeeper be 25x and 18x respectively. Number of pencil sold by shopkeeper = 13/6 × 18x = 39x So, 25x × 40 + 18x × 20 + 39x × 10 = 21000 ⇒ 1000x + 360x + 390x = 21000 ⇒ 1750x = 21000 x = 12 Number of pen sold by shopkeeper = 18x = 216
41.5% of ? + 64.69% of 419.1 = 504.2
(88.931% of 435) + (61.521% of 516) = ?
3.992 + (3.01 × 2.98) + ? = 225.03
80.08% of 1250.25 + 64.02% of 1200 = 24.02 × 36.025 + ?% of 2259.98
(27.08)2 – (14.89)2 – (22.17)2 = ?
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.)...
? 3 + 95.06 X 39.87 ÷ 5.03 = 1271.89
17.98% of (16.93 X 8.992 + 46.87) = ? of 14.92 - 26.83 of 1.98
63.981 + 64.001 + 65.08019 + 63.11112 =?
?% of (150.31 ÷ 14.97 × 50.011) = 319.98
