Question
The mode of the sample data = is 24 and the median = 80.
Find the mean of this distributionSolution
Given -mode = 24 median =80 let mean = x As we know that relation between mean, mode, and median median × 3= mode + 2 mean so 80×3 = 24 + 2x 240 = 24 +2x 2x = 240-24 =216 x= 261/2=108 mean = 108
 √256 * 4 – 30% of 190 + ? = 110% of 220
20% of 450 - 15% of 400 = 25% of ?
6612 ÷ 19 - ?% of 240 = -2196
What will come in the place of question mark (?) in the given expression?
642 - 362 = ? X √1225
If 1560 ÷ 30 + 2025 ÷ 45 - z + 33 × 7 = 1848 ÷ 24 × 234 ÷ 39, then the value of z is:
If 32x + 1 – 3x = 3x + 3 – 32, then values of x are:
(54/6) × 5 + 12 × (17/2) = ?% of 700
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?
