Let number of notes of each denomination be x.
Then x + 5x + 10x = 480
16x = 480
x = 30.
Hence, total number of notes = 3x = 90.

Suppose their paths cross after x minutes.
Then, 11 + 57x = 51 - 63x
120x = 40
x =1/3
Number of floors covered by David in (1/3) min. =1/3* 57= 19.
So, their paths cross at (11 +19) i.e., 30th floor.

Let breadth = x metres
Then, length = (x + 20) metres.
Perimeter =5300/26.5 = 200 m.
2[(x + 20) + x] = 200
2x + 20 = 100
2x = 80
x = 40.
Hence, length = x + 20 = 60 m.

Let the ten’s digit be x and unit’s digit be y.
Then, x + y = 15 and x – y = 3 or y – x = 3.
Solving x + y = 15 and x – y = 3, we get : x = 9, y = 6
Solving x + y = 15 and y – x = 3, we get : x = 6, y = 9
So the number is either 96 or 69. Hence, the number cannot be determined.

Let the initial amount with Mr. Jones be Rs x. Then,
Money given to wife = Rs. (40/100) x= Rs. 2x/5. Balance = Rs. (x-2x/5) = Rs. 3x/5
Money given to 3 sons = Rs. [3×(20/100×3x/5)]=Rs.9x/25
Balance = Rs. (3x/5-9x/25)=Rs.6x/25
Amount deposited in bank = Rs. (1/2×6x/25)=Rs.3x/25
∴3x/25=12000⇔x=((12000 × 25)/3)=100000

Quantity of water in 10 litres = 5% of 10 litres = 0.5 litres
Let x litres of pure milk be added. Then, 0.5/(10 + x)=2/100⇔2x=30⇔x=15

Let S.P = Rs.135 Then,
New S.P.=90
Let C.P= X
According to question
Gain percent at original price=135-100/100=35%

suppose he sells x oranges.Then,
C.P. = Rs.(2/3*x) = Rs.2x/3 and S.P. = Rs.x
so x -2x/3 = 10 or x = 30

Required number of ways = 4! * 3! * 2! = 288.
