Answer:

Step-by-step explanation:

a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %

b) Let the number of pies sold = x

45% of x = 90

$\dfrac{45}{100}*x=90\\\\\\x=90*\dfrac{100}{45}\\\\\\x=2*100\\$

Number of pies = 200

c) Number of cheese filling = 30% of 200

$=\dfrac{30}{100}*200\\\\= 30*2\\\\\\= 60$

Number of beef pies = 25% of 200

$=\dfrac{25}{100}*200\\\\\\=25*2\\\\= 50$

Difference = 60 - 50 = 10

There are 10 more cheese pies than beef pies.

Tan t /(sec t -cos t)= sin t/(cos t *(1/cos t -cos t))
=sin t/(cos t*(1-cos ²t)/cos t))
=sin t/sin² t=1/sin t [or=cosec t.]
