Three people check into a hotel.

They pay £30 to the manager and go to their room.

The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people.

On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person.

Now each person paid £10 and got back £1.

So they paid £9 each, totalling £27. The bellboy has £2, totalling £29.

Sum of two numbers is 1/3rd of 1/5th of 195 and product is 1/6 th of 1/4th of 960. Find 1/3 of the difference between numbers :

Reply Like? Yes | No

(9 years ago)

Let the numbers be a and b
a + b = (1/3) of (1/5) of 195 = 39
a * b = (1/6) of (1/4) of 960 = 40
solving a+b =39 and ab = 40
we get a quadratic equation a2 - 13a +40 =0
its solution is a=5,8
for this correspondingly b = 8,5
their difference:
a=8 , b=5 , a-b=3 so 1/3 of difference is 1
a=5 , b=8 , a-b= -3 so 1/3 of difference is -1

Given ratio of 50 paise & 25 paise coins as 7:3 ,So they can be 7,3 or 14,6 in quantity
With only statement (2), it is not clear about 1 Rs. coins, to get total amount
With statement (1), total coins are 20, so 50 paise & 25 paise coins should be 7 & 3 respectively , so remaining 10 coins of 1 Rs.
Total amount in the bowl= (10*1) +(7*0.5) +(3*0.25)=14.25 Rs.

Here sum can be taken of two series 1st 1,3,5,7,......,199 and 2nd -2,-4,-6,-8,......,-200 and each series will contain 100 terms out of total 200
Sum of 1st series=(100/2)[2*1 + (100-1)*2]=50*[2+ (99*2)]=10000
Sum of 2nd series=(100/2)[2*(-2) + (100-1)*-2]=50*(-202)=-10100

(1+3+5+..........)-(2+4+6+......).they both are in a.p.
so odd series will have 100 terms and even series will have 99 terms by using the formula tn=a+(n-1)d.so sum of the terms in a.p.,when their ends are known is,sum=n/2(a+l).
so sum=50(200)+99/2(202)=10000-9999=1

we get gain by 3.12%..
let the amounts are 300:500.
gaining 25% will gives 375,losing 10% results 450,adding together gives 825.
diff is 825-800=25.
gain=(25/800)*100=3.125%

Raj drives slowly along the perimeter of a rectangular park at 24kmph & completes 1 full round in 4 mins. If ratio of length to breadth of park is 3:2. Wat are its dimensions

480 m. & 320 m.

If length=3x and Breadth=2x, then distance along the perimeter of rectangle=2(3x+2x)=10x
With the speed of 24 Kmph, distance covered in 4 min.=4*24/60=8/5 Km.
As here,10x=8/5 Km., so x=8/50 or 4/25 Km.
So dimension of park are length=3x=3*4/25=12/25 Km. or 12*1000/25=480 m. and
breadth=2x=2*4/25=8/25 Km. or 8*1000/25=320 m.

The correct answer is: Rs. 15, 600

169P/144 = P(1+(r/100))^2

r= 100/12
p=14400
ci = 14400(1+1/12)=15600
