Answer:
15%
Step-by-step explanation:
Let
Selling price = SP
Cost price = CP
If CP = 100
Profit = selling price - cost price
x% = SP - x% of 100
x% + 100x% = SP
SP = 100 (1 + x/100) (1)
If CP = 92
SP = 92 (1+ {x+10}/100)
Equate both SP
100 (1 + x/100) = 92 (1+ {x+10}/100)
100 + x = 92 + [{23/25} * (x+10)]
{2/25}x = 30/25
x = 30/25 ÷ 2/25
= 30/25 × 25/2
= 30/2
x = 15%
2/9 × 3 =
= 2×3 / 9 =
= 6/9 =
= 2/3
11/12 is greater than 2/3.
Answer:
Option B
Step-by-step explanation:
the mean is the sum of each value of P(x) multiply for x
Mean= 23x0.16 + 25x0.09 + (26x0.18) + (31x0.12)+ (34x0.24) + (38x0.21)
Mean= 30.47
