If I divide the coins into two unequal numbers, then 48 times the difference between the two numbers equals the difference between the square of the these numbers.” Girlfriend looked puzzled. Can you help her by finding out how many gold coins boyfriend has?

Ans :48

Exp :Two unequal numbers : x and y

48(x-y)=x^2 – y^2

ð                      x+y=48

7) The owner of a jewellery shop hired 3 watchmen to guard his diamonds, but a thief still got in and stole some diamonds. On the way out, the thief met each watchman, one at a time. To each he gave ½ of the diamonds he had then, and 2 more besides. He escaped with one diamond. How many did he steel originally.

Ans :36

Exp :No. of diamonds before he gave some diamonds to the third watchman = x-(x/2+2)=1

ð              X-4/2=1  àx=6

Hence he had 6 diamonds before he gave 5 to the third watchman.

Similarly, x-4/2=6  à x=16 (number of diamonds before giving to second watchman)

And also x-4/2=16 à x=36

Therefore, thief stole 36 diamonds

8) 480, 240, 720, 180, 900, 150, ?

Ans :1050

Exp: 480, 480/2=240, 240*3=720, 720/4=180, 180*5=900, 900/6=150, 150*7=1050

10)What is the angle between the minute hand and the hour hand when the time is 03:40 hours?

Ans: 130

The total angle made by the minute hand during an hour is 360^o. If it takes 360^o for an hour, it will take 40/60*360= 240^o. The angle between the hour hand the minute hand will therefore, be somewhere between 240 - 90 = 150^o, as the hour hand is between 3 and 4.
The angle made by the hour hand when it moves from say 3 to 4 will be 30^o. That is the hour hand makes 30^o during the course of an hour.
The hour hand will therefore, move 40/60*30= 20^o.
Therefore, the net angle between the hour hand and the minute hand will be 150 - 20 = 130^o.
