Let the P=x A =287 SI =287-x 287-x =(x×5×8)/100 287-x =40x /100 140x =28700 x =205Rs.
28 + √144 + 144 ÷ (3)2 = ? - 4
(6630 ÷ 13 + 6120 ÷ 12) ÷ (17 × 3) = ?
648 ÷ 36 × 49 – 1012 + 847 = ?
1.55 + 2.05 + 1.5 × 11 – 20% of 10.5 = ?
30% of 60% of 1800 + 13 × 14 = (? ÷ 75) × 5
262 × 15 + (?)² = 4099
132 × 3 ÷ 11 + 67 − ? = 64 ÷ 8 × 2
