3. The total expense of a boarding house are partly fixed and partly variable with the number of boardeRs. The charge is Rs. 70 per head when there are
25 boarders and Rs. 60 when there are 50 boardeRs. Find the charge per head when there are 100 boardeRs.
A) 65 b) 55 c) 50 d) 45
solution:-
a = fixed cost and
k = variable cost and n = number of boarders
total cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
total cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
solving above 2 eQuestions, 3000-1750 = 25k i.e. 1250 = 25k i.e. K = 50
therefore, substituting this value of k in either of above 2 eQuestions we get
a = 500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
so total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
so cost per head = 5500/100 = 55
4. Amal bought 5 pens, 7 pencils and 4 eraseRs. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what amal had
paid. What % of the total amount paid by amal was paid for pens?
A) 37.5% b) 62.5% c) 50% d) none of these
solution:-
Let, 5 pens + 7 pencils + 4 erasers = x rupees
so 10 pens + 14 pencils + 8 erasers = 2*x rupees
also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees
so (10-6) = 4 pens = (2-1.5)x rupees
so 4 pens = 0.5x rupees => 8 pens = x rupees
so 5 pens = 5x/8 rupees = 5/8 of total (note x rupees is total amt paid by
amal) i.e 5/8 = 500/8% = 62.5% is the Answer
5. 2 oranges, 3 bananas and 4 apples cost Rs. 15. 3 oranges, 2 bananas, and 1 apple costs rs 10. What is the cost of 3 oranges, 3 bananas and 3 apples?
A) 10 b) 20 c) 30.45 c) 15
solution:-
2x+3y+4z=15
3x+2y+z=10
adding
5x+5y+5z=25
x+y+z=5 that is for 1 orange, 1 bannana and 1 apple requires 5Rs.
So for 3 orange, 3 bannana and 3 apple requires 15Rs.
I.e. 3x+3y+3z=15
