Let the incomes of Vineet and Vidya be Rs. 8x and Rs. 5x respectively. According to the question, => 0.70 x 8x + 0.80 x 5x = 19200 => 5.6x + 4x = 19200 => x = 2000 Required difference = 8x – 5x = 3x = Rs.6000
Find the approximate value of Question mark(?). No need to find the exact value.
18.07 × (47.998 ÷ 12.03) + 59.78% of 150.14 – √(255.86) = ...
22.11 × 4.98 + 23.03 × 5.12 – 32.95 + 96.9 × 5.02 =?
58.03% of 1499.99 - ? % of 699.95 = 394.04
(3375)1/3 x 12.11 x 6.97divide; 14.32 = ? + 15.022
10.232 + 19.98% of 539.99 = ? × 7.99
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.)...
(27.08)2 – (14.89)2 – (22.17)2 = ?
