ATQ, (a+b+c)/3 = d-8 a+b+c = 3d-24 a+b+c+d=42×4=168 3d-24+d = 168 4d=168+24 ∴ d=192/4 d =48 and again, b+c = 2 × 43 b+c = 86 a + b + c = 3d-24 = 144-24 =120 a = 120-86 = 34 average of (a-6) and (d+2) = ½ [(68-6) + (48+2)] = 112/2 = 5 6
276 ÷ 11.5 + 12 = ? x 3
What will come in the place of question mark (?) in the given expression?
{(2/15) + (12/25)} of 375 + 190 = ?% of 375
(1225/25) - (192/96) + (50/5) = ?
[123 ÷ 8 ÷ 9] × 144 = ? + 12 × 5
2 X 25 + (30% of 80) ÷ (10% of 120) = ?
What is the value of 143 + 163 + 183 + … + 303?
{(? × 15) + (? × 45)} – 120 = 360
Find the value of {(3125) (n/5) × 5 (2n + 2) }/ {25 n × 5 (n - 1) }
