Step-by-step explanation:
cost of an egg= 900/100= Rs.9
Total cost = 100×9=Rs.900
when 8 eggs broken, the eggs remained to sell is 92(100-8)
Total sales = 10.50×92=Rs.966
profit = total cost-total sales
profit =966-900= Rs.66
profit percentage =profit/total sales×100%
66/966×100%=6.832%

<u>The correct answer is A. - 11 square root of 7.</u>
Step-by-step explanation:
We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.
Let's simplify it:
2 √28 - 5 √ 63
2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)
2 * 2 √7 - 5 * 3 √ 7
4 √7 - 15 √7
- 11 √7
<u>The equal expression is A. - 11 square root of 7.</u>
