Question
I. 7x + 8y = 36 II. 3x + 4y =
14Solution
7x + 8y = 36 .......................(i) 3x + 4y = 14 .......................(ii) Multiplying equation (ii) by 2 We get 6x + 8y = 28.......................(iii) By solving (i) and (iii) => x = 8 => y = -2.5 Hence, x > y.
√4761 ÷ 23 + √12769 = ? × 58
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)

What will come in the place of question mark (?) in the given expression?Β
435 Γ· 29 X 792 Γ· 44 = β(? + 14) + 35 + 221 Γ· 17
...? = 65% of 40% of (20 Γ 250) β 200
[4(1/2) + 4(1/3)] Γ 12 β 42 = ?2
