LCM × HCF = a × b a = First number b = Second number LCM × 325 = 6453 × 7122 LCM = 141410
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
65% of ? = 50 + 20 × 4
√? × 4 - 374 + 127 + 300 = 117
40500 ÷ 30 × 42 – 45% of 2400 =? + 42100
(√1024 + √324)% of 780 = ?% of 260
?% of (√196) × 24 + 344 = 428
