Let the income of Aman and Rahul = 5x and 4x and expense of Aman and Rahul = 3y and 2y ATQ- 5x -3y = 1600 ... (1) 4x -2y =1600 ... (2) Eq (1) multiplied by 2 and Eq (2) multiplied by 3. 10x -6y =3200 12x-6y=4800 Eq (2)-Eq (1) 2x = 1600 x =800 Total income of Aman =5x =5×800 = 4000 Rs
25% of 160 × 18 = ? – 24
4.7 × 3.5 + 4.2 × 4.5 = 22.5 × 3.5 - ?
15% of ? = 30% of 320 + 17 ×√676 – 63.5 × 8
28 × 3.5 +25 × 3.2 = ? - 62
8(3/4) + 5(1/6) – 4(3/4) = ?
15% of 360 × 20% of ? = 324
What will come in the place of question mark (?) in the given expression?
(50 × 6 ÷ 12) × 9 = ?
(72 + 30) ÷ 6 + [{75 ÷ 25) + 6} × 2] = ?
(21 × 16 – 8) ÷ 41 = ?
