ATQ, Let, income of ‘Arjun’ and ‘Bhanu’ be Rs. 'a' and Rs. 'b' respectively. So, 0.6a = 0.5b Or, a/b = 5/6 Let, a = 5k, b = 6k Savings of ‘Arjun’ = (1 – 0.75) × 5k = Rs. (5k/4) Savings of ‘Bhanu’ = (1 – 0.8) × 6k = Rs. (6k/5) Required ratio = (5k/4):(6k/5) = 25:24
(9/20 of 3998.93) - √2499.57 + (17.87% of 1199.67) = ?
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 × 9.05 = ?
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.)...
(23.95)2– (25.006)2+ (8.0099)2– (7.07)2= ? - (14.990)2
(8000)1/3 × 10.11 × 8.97 ÷ 18.32 = ? + 25.022
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
19.92 × (52.065/260.07) × (45.09% of 359.87) =?
(519.98 + ?) ÷ 13.01 = √440 + 20.0
What will be the approximate value of the following questions.
(√143.74 + 29.89% of 720.27) × (5/9 of 539.79) = ?
(3.21) ? + 37.92 ÷ 1.98 = (5.99 + 3.99) 2
