B + ( B/4 ) * 7 + [( B*2 ) – ( B-2 ) ( B-2 )] + 5 – ( B*B ) = B

**What is the value of B?**

Puzzle by : Pranav Tambat

Check your answer:-

Lets say B is half full blue glass, Y is half full yellow glass and R is half full red glass, then

2B + B + 2B = 15 => 5B = 15 => B = 3

2Y – Y + 2B = 10 => Y + 2*3 = 10 => Y = 4

2R + 2R – R = 6 => 3R = 6 => R = 2

Now

B + (B+R)*Y = 3 + (3+2)*4 => 3 + 20 => 23

somewhere in the wonder land there are sequence of 7 Temples separated by 7 rivers,

Sequence is Temple, River, Temple, River…………

A man has to put equal number of flowers on every temple but the catch is as he crossed the river, remaining flowers will be doubled (2 times)

how many flowers should a man carry with him before entering into first temple so that till last river he has left with nothing?

Assume he took 5 flowers,

on first temple he drop 2, remaining is 3 as he crossed the river it will become 6, he put same number of flowers (i.e 2 flowers) 6-2=4 which again become twice in second river means 8…

I tried so many ways but cant get the answer?

Hope someone else come up with some good logical based answer

prove that 7 + sinx/n=13

Only genius can solve this 🙂

SolutionHide

7 + sinx/n=13

here n is common between numerator and denometor thus

7 + six = 13

7 + 6 = 13

13 = 13

LHS = RHS

hence proved

Let me see how clever everyone is…

Solve the riddle :

Think properly and then answer

Check your answer:-

one 9 in every 10s (like 9, 19, 29, etc) => 10

extra 10 9s in 90 – 99 => 10

thus total 20

extra 10 9s in 90 – 99 => 10

thus total 20

One-tenth of the cars in a car park are yellow. Another car arrives and now one-ninth of the cars are yellow.

Check your answer:-

lets say there are total x cars, thus

x/10 number of cars are yellow initially.

x/10 number of cars are yellow initially.

as yellow car’s percent increases from 1/10th to 1/9th after new car arrives, so new car must be a yellow car.

So we can form this equation

1 + x/10 = (x+1)/9

Now we just need to solve this equation

on multiplying both sides by 9*10 =>

9*10 + 9x = 10x + 10

90 – 10 = 10x – 9x

x = 80

So there were 8 yellow cars initially among a total of 80 cars(i.e. 1/10th)

and a new yellow cars comes making 9 yellow cars in total of 81 cars.(i.e. 1/9th)

So **answer to the question is 81**. there are a total of 81 cars now.

A shopkeeper gives a full bottle of soft drink in return for five empty bottles. A guy has 77 empty bottles and he can use them to get full soft drink bottles.

How many filled bottles will he be able to collect?

What will be the value of Yellow flower + Red flower*Blue Flower?

Check your answer:-

Answer With Explanation**Explanation**:

from first equation red flower = 20

from second equation blow flower = (30 – 20)/2 = 5

from third equation 5 – 2yelloflower = 3 => yello flower = (5-3)/2 = 1

Thus Yellow flower + Red flower*(Blue Flower with four petals)

yes thats the catch, blue flower with 4 petals should be of value 4

= 1 + 20 *4 = 81, remember BODMAS rule, multiplication first.
