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
118 × 6 + 13 + 83 = ?
What will come in the place of question mark (?) in the given expression?
(55 × 8 + 28) × 10 = ?
(13 X 11) + (19 X 3) = 400% of √?
135÷ 15 x 19 + 14807 = ? + √3249 - √9604
1240 ÷ ? = 242 + 123 – 514 × 4
(√7225 x √1225)/(√625) = ?
(512) (2/3) × √64 ÷ (512) (1/3) = (64) (?/2) ÷ (2)6
1/6+ 999*53/54 ×9 = ?
26 X √25 + 15 - 80% of 120 = ?2
540240 ÷ 24 ÷ 25 =?
