**Question 1.**

**Solution:**

(i) C.P. = Rs. 950

**Question 2.**

**Solution:**

(i) CP = Rs. 2400

SP = Rs. 2592

Gain = SP – CP = Rs. 2592 – Rs. 2400 = Rs. 192

**Question 3.**

**Solution:**

(i) S.P. = Rs. 924

Gain% = 10%

**Question 4.**

**Solution:**

C.P. of an almirah = Rs. 13600

Amount spent on transportation = Rs. 400

Total cost price (CP) = Rs. 13600 + Rs. 400 = Rs. 14000

SP = Rs. 16800

Total gain = SP – CP

= Rs. 16800 – Rs. 14000 = Rs. 2800

**Question 5.**

**Solution:**

CP of an old house = Rs. 765000

Amount spent on repairs = Rs. 115000

Total cost price (CP) = Rs. 765000 + Rs. 115000 = Rs. 880000

Gain = 5%

**Question 6.**

**Solution:**

CP of 1 dozen or 12 lemons = Rs. 25

SP of 5 lemons = Rs. 12

**Question 7.**

**Solution:**

SP of 12 pens = CP of 15 pens

Let CP of 1 pen = Re. 1

The CP of 15 pens = Rs. 15

and SP of 12 pens = Rs. 12

**Question 8.**

**Solution:**

SP of 16 spoons = CP of 15 spoons

Let CP of 1 spoon = Re. 1

Then CP of 15 spoons = Rs. 15

and SP of 16 spoons = Rs. 15

**Question 9.**

**Solution:**

For Manoj

CP of video = Rs. 12000

Gain = 10%

**Question 10.**

**Solution:**

SP of sofa set = Rs. 21600

Gain = 8%

**Question 11.**

**Solution:**

SP of a watch = Rs. 11400

Loss = 5%

**Question 12.**

**Solution:**

SP of calculator = Rs. 1325

Gain = 6%

**Question 13.**

**Solution:**

SP of computer = Rs. 24480

Loss = 4%

**Question 14.**

**Solution:**

In first case gain =15%

and in second case, gain = 20%

Difference = 20 – 15 = 5%

Now 5% of the CP = Rs. 108

CP = \(\frac { 108 x 100 }{ 5 }\) = Rs. 2160

**Question 15.**

**Solution:**

In first case, loss = 8%

and in second case gain = 6%

Difference = 8 + 6 = 14%

Now 14% of CP = Rs. 3360

CP = Rs. \(\frac { 3360 x 100 }{ 14 }\) = Rs. 24000

**Question 16.**

**Solution:**

SP of first cycle = Rs. 2376

Gain = 10%

**Question 17.**

**Solution:**

SP of an exhaust fan = Rs. 7350

**Question 18.**

**Solution:**

Let CP of watch for Mohit = Rs. 100

Gain =10%

SP for Mohit = Rs. 100 + 10 = Rs. 110

CP for Karim = Rs. 110

Gain = 4%

**Question 19.**

**Solution:**

Retail price or S.P. of the machine for retailer = Rs. 37950

Gain = 25%

**Question 20.**

**Solution:**

CP of video = Rs. 20000

and CP of television = Rs. 30000

Loss on video = 5%

and gain on TV = 8%

Total CP of video and TV = Rs. 20000 + 30000 = Rs. 50000

and SP of video and TV = Rs. 190000 + 32400 = RS. 51400

Gain = SP – CP = Rs. 51400 – 50000 = Rs. 1400

**Question 21.**

**Solution:**

SP of 36 oranges = CP of 36 oranges – loss = CP of 36 oranges – SP of 4 oranges

⇒ SP of 36 oranges + SP of 4 oranges = CP of 3 6 oranges

⇒ SP of 40 oranges = CP of 36 oranges

Let CP of each orange = Re. 1

CP of 36 oranges = Rs. 36

and SP of 40 of 40 oranges = Rs. 36

**Question 22.**

**Solution:**

We know that C.P. = S.P. – gain

C.P. of 8 dozen pencils = S.P. of 8 dozen pencils – S.P. of 1 dozen pencils

= S.P. of 7 dozen pencils = Rs. 100 (suppose)

C.P. of 1 dozen = Rs.\(\frac { 100 }{ 8 }\)
