<h2>|| <u>Question</u> ||</h2>
John purchased 24 chocolates for Rs.96. How many chocolates can be purchased for Rs.72?
<h2>|| <u>Answer</u> ||</h2>
John purchased 24 chocolates = Rs.96.
Chocolates can be purchased for Rs.72 = x
<h3>

</h3>
24:96 = x:72
Means = Extreams
96 × x = 24 × 72
<h3>

</h3>
( 12 × 2 = 24, 12 × 8 = 96 )
<h3>

</h3>
(8 × 1 = 8, 8 × 9 = 72)
<h3>

</h3>
Therefore, 18 chocolates can be purchased for Rs.72
Two decimals between are -2.5 and -2.3
Answer:
x = 7, y = 24
Step-by-step explanation:
23x -16 + 8x - 21 = 180 because they are supplementary angles
31x - 37 = 180
31x = 217
x = 7
23(7)-16 = 7y - 23 because they are vertical angles
168 = 7y
y = 24
