Answer:
<em>Number of story books bought = 100
</em>
<em>
C.P. of each book = Rs. 135
</em>
<em>
C.P. of all 100 books = Rs. (135×100)= Rs. 13500
</em>
<em>
C.P. of 90 books = Rs. (135×90)= Rs. 12150
</em>
<em>
Number of books donated = 10
</em>
<em>
Number of books sold = 100-10=90
</em>
<em>
Loss% in the transaction = 2%
</em>
<em>
S.P. of all books = (C.P./100)(100-loss%)
</em>
<em> =Rs. (12150/100×98)
</em>
<em>
Thus, S.P. of each book
</em>
<em>
= Rs. {(12150/100×98)÷90}
</em>
<em>
= Rs. (12150/100×98/90)
</em>
<em>
= Rs. 132.3</em>
Answer:
m∠TUW = 90, m∠VUR = 130, m∠VUW = 50
Step-by-step explanation:
Supplementary angles add up to 180!
The interior angles of a triangle need to be equal to 180°, so to solve this you need to figure out how many degrees you need to get 180°.
46 + 61 = 107
180 - 107 = 73
The measure of the third angle is B. 73°.
Answer:
Less than $12
Step-by-step explanation:
I changed everything into decimals to make it easier to solve:
1 2/5= 1.4
2 3/10= 2.3
1.4+2.3=3.7
2.99·3.7=11.063 (Round it to the nearest hundredth and you get 11.06)
You mean the product of 0.5 and 1.7 which is 0.85.
