The ratio between the length and breadth of a rectangular board is 7:5. If the breadth of the board is 20.5cm, find the length in cm.
let length be 7x breadth be 5x breadth = 20.5 cm Now, 5x = 20.5 x = 4.1 cm Hence, Length = 7 x 4.1 = 28.7 cm
(23 × 8) – (13 × 5) + 67 =? x 6
140% of 9/8 of ? = 108% of 2800
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
The value of 97 × 103 is _________.
212.3 × 4414.7 × 4623.4 × 4845.85 = 462?
((67)32 × (67)-18/ ? = (67)⁸
33 × ?2 – 6 × 5 = 3270
{(? × 15) + (? × 45)} – 120 = 360
(3/7) x 868 + 25% of 240 = (? + 65)
