**Question-1****Explanation**

**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.**

**Options :**

a) Rs. 45000

b)Rs. 5000

c)Rs. 4000

d)Rs. 5500

**Answer: ** ** c) Rs. 4000**

Meena and Sonu invested Rs. 15.000 and Rs. 12.000

Respectively.

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

**Question-2****Explanation**

**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?**

**Options :**

a)Rs. 1,000

b)Rs. 2000

c)Rs. 1,500

d)Rs. 1,800

**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

**Question-3****Explanation**

**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:**

**Options :**

a)Rs. 30,000

b)Rs. 25,000

c)Rs. 25,400

d)Rs.29,400

**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

3X=72,000

Then X-24,000

A:B:C:=24000:34000:42,000=12:17:21

Then c’s share=(21/50)*70,000=Rs.29,400

**Question-4****Explanation**

**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?**

**Options :**

a) Rs. 20409

b)Rs. 21009

c)Rs. 21429

d)Rs. 21400

**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}

=Rs. 330X400+98X/400

=Rs. 428X/400

Since the total cost price is Rs. X and the total profit is Rs.1500 then Rs.428X/400-X=Rs. 1500

28X=1500X400=Rs.6,00,000

X=6,00,000/28=Rs.21428.57=Rs.21429

Hence the answer is Rs. 21429

**Question-5****Explanation**

**Meera sold 8 keys and makes a profit equal to the selling price of 2 keys. What is the profit percentage?**

**Options :**

a)33(1/3)%

b)35(1/3)%

c)33%

d)35%

**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)%

**Question-6****Explanation**

**if the profit is 40% and Rs. 500 is the fdifference between c.p and s.p then c.p is:**

**Options :**

a) Rs. 1750

b)RS.1250

c)Rs.1500

d)Rs.1800

**Answer: ** ** b)Rs. 1250**

Solution:

Let c.p be Rs.X then s.p=Rs.140% of X=Rs. 14X/10

Now, 14X/10-x=Rs.500

4X=Rs.5000

X=Rs.1250

s.p=Rs. 14*1250/10=Rs. 1750

Hence the c.p is Rs. 1250
