Question

23+4=24;21+5=20;34+6=48;41+2=12;52-7=?

Answer 1

Answer:

56

Step-by-step explanation:

23+4=24->[(2+3)*4+4=24]

21+5=20->[(2+1)*5+5=20]

34+6=48->[(3+4)*6+6=48]

41+2=12->[(4+1)*2+2=12]

52-7=56->[(5+2)*7+7=56]

Answer 2

-56

In puzzles, to find out the missing number, the first step is to find the logical pattern of the puzzle from the given data.

The given data is,

• 23+4=24
• 21+5=20
• 34+6=48
• 41+2=12
• 52-7=?

First step: Finding out the logical pattern

here, the logical pattern is [(A+B)C]+C

• In 23+4=24, [(2+3)4]+4 = [(5)4]+4 =20+4=24
• In 21+5=20, [(2+1)5]+5  =  [(3)5]+5 =15+5=20
• In 34+6=48, [(3+4)6]+6 =  [(7)6]+6 =42+6=48
• In 41+2=12,  [(4+1)2]+2   =  [(5)2]+2 =10+2=12

In the same pattern, 52-7=?

[(5+2)(-7)]+(-7) = [7(-7)]+(-7) = -49-7 = -56

In this puzzle, the value of 52-7 is -56
