however you can get the value by doing
Eq3 – Eq2 + Eq1
thus the answer will be 27 – 24 + 21 => 24

B1 + B2 = 14
B1 + B3 = 15
B2 + B4 = 16
B3 – B4 = 10
by adding all equations
B1 + B2 + B3 = (14 + 15 + 16 + 10 )/2 = 55/2 = 27.5
B3 = 27.5 – (B1 + B2) = 27.5 – 14 = 13.5 => B3 = 13.5
B2 = 27.5 – (B1 +B3) = 27.5 – 15 = 12.5 => B2 = 12.5
B1 = 14 – B2 = 14 – 12.5 = 1.5 => B1 = 1.5
B4 = B3 – 10 = 13.5 – 10 = 3.5 => B4 = 3.5
Let’s see if you can solve this one.
What is the heigh of the table in cm?
Check your answer:-
let’s write down the equations
T + C – R = 170cm
T + R – C = 130cm
add both the equations
2T + C – R + R -C = 170 + 130 cm
2T = 300cm
T = 150cm
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

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:-
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.
