Answer is 71

as numbers add upto a multiple of 10 in every atom.

ex. 0 + 3 + 14 + 2 +1 =20

2 + 10 + 24 + 6 + 8 = 50

only option which can make the sum to a multiple of 10 for 4 + 14 + 5 + 6 is 71.

Click here to See SolutionHideLet’s quickly write the equations

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 assume height of the table is T and cat is C and R of tortoise.

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

Five Clues

**7 2 5**: 1 number is correct and placed in the wrong spot**3 1 7**: 2 numbers are correct and placed in the wrong spot**7 9 3**: 1 number is correct and placed in the proper spot**8 4 9**: nothing is correct.**8 9 1**: 1 number is correct and placed in the wrong spot.

Check your answer:-

from clue 3 and 4 -> 1 number can be 7 OR 3 (since 9 is not correct). Now if 7 was correct and placed in proper spot, it conflicts with Clue 1, thus 7 can’t be the correct number and the correct number is 3 and placed at proper spot (which is 3rd spot).

Now from 2nd clue -> two numbers are correct, one is 3 and other one should be 1 (as we know 7 can’t be correct number), since 1 is placed at wrong spot, correct spot for 1 should be first (since 3rd spot is for 3).

Again from Clue 1: 1 number is correct and placed at wrong spot. we are looking for a number at 2nd spot, it should be 5 (as 7 is not in picture and it can’t be 2 since it is placed at 2nd spot), 5 is placed at wrong spot, its correct spot should be 2nd, since we already know 1st and 3rd spot numbers.

Thus the PIN is 153.
