Answers
Step-by-step explanation:
Consider the provided information.
Let he number of eggs sold on Monday, Tuesday, and Wednesday is x, y, and z.
The number of eggs sale on Thursday is 42.
Monday, Tuesday and Wednesday in the shop was 43.
Total egg sale on Monday, Tuesday and Wednesday are 43×3=129
Thus, x+y+z=129 .....(1)
The average of Tuesday, Wednesday and Thursday was 45.
y+z+42=135
Simplify above equation.
y+z=135-42
y+z=93
Now substitute the value of y+z in equation 1.
x+93=129
x=129 -93
x=36
Hence, the sale on Monday was 36 eggs.
Answer:
Let he number of eggs sold on Monday, Tuesday, and Wednesday is x, y, and z.
The number of eggs sale on Thursday is
42.
Monday, Tuesday and Wednesday in the shop was 43.
Total egg sale on Monday, Tuesday and
Wednesday are 43 * 3 = 129
Thus, x + y + z=129......(1)
The average of Tuesday, Wednesday and Thursday was 45.
y + z + 42 = 135
Simplify above equation.
y + z = 135 - 42
y + z = 93
Now substitute the value of y+z in equation 1.
x + 93 = 129
x = 129 - 93
x = 36
Hence, the sale on Monday was 36 eggs.
