BRAIN EXERSISE
Here i am posting some math based brain exercise, Just tease your brain.... (Answers are at the end..) First question: 2 CATS + 1 DOG = 10 2 CATS + 2 DUCKS + 1 DOG = 22 2 DUCKS + CAT = 15 WHAT IS THE VALUE OF QUESTION MARK IF : 4 CATS + 1 DUCK + 2 DOGS = ? __________________________________________________________________________________ Second question: Third question: FORTH QUESTION: __________________________________________________________________________________ ANSWERS :- 1. TAKE SECOND EQUATION : 2 CATS + 2 DUCKS + 1 DOG = 22 = [2 CATS + 1 DOG] + 2 DUCKS = 22 ; HERE WE CAN REPLACE '2 CATS + 1 DOG' WITH 10 AS GIVEN IN FIRST EQUATION. = 10 +2 DUCKS = 22 = 2 DUCKS = 22-10 =12 = 1 DUCK = 12\2=6 SO,1 DUCK= 6 NEXT IF WE MOVE TO THIRD EQUATION: 2 DUCKS + 1 CAT = 15 ; HERE WE CAN REPLACE '2 DUCKS' WITH 12[6 X 2] WHICH WE GOT FROM SECOND EQUATION.
