Profit = 450 * 40 /100 = 180

If selling price of 600 articles is = Rs. 630

Then the selling priceof one article will be = Rs. 630/600

Selling Price of 630 articles = 630/600 * 630 = Rs. 661.5

Profit = 661.5 – 450 =Rs. 211.5

Profit % = 2115 / 4500 *100 = 47% - Question 44 of 50

**A gold ring of 20 gm has gold and silver in the ratio 196:4 ,while another ring of 10 gm has in the ratio 8:2 .If both of them are molten and mixed together. Find the ratio of gold and silver in the resultant mixture?**CorrectAmt. of gold in the first gold ring = (196/196+4)*20 = 19.6 gm

Amt. of silver in the first silver ring = (4/196+4)* 20 = 0.4 gm

Amt. of gold in the second gold ring = (8/ 8+2)* 10 = 8 gm

Amt. of silver in the second silver ring =(2/ 8+2) *10 = 2 gm

Therefore , ratio of gold : silver = (19.6+8) / (0.4 + 2) = 23/2IncorrectAmt. of gold in the first gold ring = (196/196+4)*20 = 19.6 gm

Amt. of silver in the first silver ring = (4/196+4)* 20 = 0.4 gm

Amt. of gold in the second gold ring = (8/ 8+2)* 10 = 8 gm

Amt. of silver in the second silver ring =(2/ 8+2) *10 = 2 gm

Therefore , ratio of gold : silver = (19.6+8) / (0.4 + 2) = 23/2 - Question 45 of 50

**In how many ways the letters of the word “EQUATION” can be arranged if it always starts with letter “E” and ends with letter “T”**CorrectFor this ,lets fix the letter E at the first position= 1! Way and fix T at the last position = 1! Way .

Now, remaining rest empty positions ie. 6 so we can arrange it in 6 different ways = 6! Ways

Hence , 1* 6! * 1= 720IncorrectFor this ,lets fix the letter E at the first position= 1! Way and fix T at the last position = 1! Way .

**A , B and C hired a meadow jointly for the whole year. A puts 80 cows for 10 months, B puts 100 cows for 6 months and C puts 120 cows for 3 months. If A paid Rs. 400 as rent. Find the total rent for the meadow ?**CorrectFind the ratio first ,

80*10 : 100 * 6 : 120 * 3

800 : 600 : 360

20 : 15 : 9

Therefore , Total rent of the meadow = 400/ 20 *44 =Rs. 880IncorrectFind the ratio first ,

80*10 : 100 * 6 : 120 * 3

**A tank has two pipes. The first pipe can fill it in 45 minutes and the second pipe can empty it in 1 hour. In what time will the empty tank be filled if the pipes be opened one at a time in alternate minutes?**CorrectIn 2 minutes -> +4 filled and -3 emptied = 1 litre filled

1 litre in 2 mins.

176 litres -> 176 * 2 = 352 mins.

Remaining 4 litres will be filled in 1 minute = 352 + 1= 353 minutes = 5 hrs 53 mins.IncorrectIn 2 minutes -> +4 filled and -3 emptied = 1 litre filled

1 litre in 2 mins.

176 litres -> 176 * 2 = 352 mins.
