Since, HCF of given numbers is 15. So, numbers are 15 x 2 = 30, 15 x 5 = 75 and 15 x 6 = 90 30 = 2 x 3 x 5 75 = 3 x 5 x 5 = 3 x 52 90 = 2 x 3 x 3 x 5 = 2 x 32 x 5 Therefore, required LCM = 2 x 32 x 52 = 450
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
40% of (362 ÷ 0.05) = ?
10³ = (? – 6) × 320 ÷ 8
(5/8 + 7/12) x 168 = ? + 93 - 25
12.5% of (100 + ?) = 40
[(15)³ × (8)²] ÷ (90 × 6) = ?²
? = (22% of 25% of 60% of 3000) + 21
95% of 830 - ? % of 2770 = 650
5(? + 2) = 3125
808 ÷ (128)1/7 + 482 = 4 × ? + 846
