Meena and Sonu enter into a business with capital Rs. 15.000 and Rs. 12,000 and they made a total profit of Rs. 9,000. Find the percentage of sonu’s share.
a) Rs. 45000
Answer: c) Rs. 4000
Meena and Sonu invested Rs. 15.000 and Rs. 12.000
The ratio of their investment is =15,000: 12,000=5.4
Total profit is Rs.9000
Sonu’s share=Rs.[4/9*9000]=Rs. 4000
Hence the answer is Rs. 4000
Subha and her friend invested in the ratio 5: 3 in a business. If 4% of the profit is given to charity and Subha’s share is Rs. 1,200 then what will be the total profit?
Answer: b) Rs. 2000
Let the total profit be Rs. 100
4% of profit is for charity,
Subha’s share=Rs.[(100-4)*(5/8)]=[96*(5/8)]=Rs. 60
If subha’s share is Rs. 60 then the total profit=Rs. 100
If Subha’s share is Rs. 1,200 then total profit=Rs.[(100/60)*1200]=Rs. 2,000
Hence the answer is Rs. 2,000
A,B,C starts a business with investment of Rs. 1,00,000
C invest Rs. 8,000 more than B and B invest Rs. 10,000 more than A , if the total profit is Rs. 70,000 then c receives:
Answer: d) Rs. 29,400
Let A ‘s investment be X
Then , B’s =X+10,000 and C’s=X+10,000+8,000
Now the total investment=X+X+10,000+X+10,000+8,000=3X+28,000
From the given data,3X+28000=1,00,000
Then c’s share=(21/50)*70,000=Rs.29,400
A seller sold his articles in two types such that three fourth at a profit of 10% and the remaining at loss of 2% . if the total profit was Rs. 1500, what ws the total value of the articles?
a) Rs. 20409
Answer: c) Rs. 21429
Let the total value be Rs. X.
The value of ¾ th=Rs. 3X/4 then the value of ¼ th=Rs. X/4
Selling price=Rs.[110%of 3X/4]+[98%of X/4}
Since the total cost price is Rs. X and the total profit is Rs.1500 then Rs.428X/400-X=Rs. 1500
Hence the answer is Rs. 21429
Meera sold 8 keys and makes a profit equal to the selling price of 2 keys. What is the profit percentage?
Answer: a) 33(1/3)%
By observing the given data we can have
S.P of 8 keys-C.P of 8 keys=profit=s.pof 2 keys then
S.P of 6 keys=C.P of 8 keys—-eq1
Let c.p of each key be Re.1
Then c.p of 8 keys=Rs. 8
And s.p of 6 keys=Rs.8(sung eq 1)
Now , the percent profit is =(2/6*100)%=100/3%=33(1/3)%
if the profit is 40% and Rs. 500 is the fdifference between c.p and s.p then c.p is:
a) Rs. 1750
Answer: b)Rs. 1250
Let c.p be Rs.X then s.p=Rs.140% of X=Rs. 14X/10
s.p=Rs. 14*1250/10=Rs. 1750
Hence the c.p is Rs. 1250
