Question

who can Answer this? with step by step like 10+10+10 then etc. only for genius ​

Answer 1

Answer:

your answer will be 20.

Step-by-step explanation:

10 + 10 + 10 = 30

5 + 5 + 10 = 20

4 + 4 + 5 = 14

10 + 5 × 2 = 20

Answer 2

Answer:

Let us take a pair of shoes' value as x.

Therefore, x + x + x= 3x= 30

⇒ x= 30/3 = 10

Now let us take one child = y.

So y + y + 10 = 20

Therefore 2y + 10 = 20

⇒ 2y = 10

⇒ y= 10/2= 5

Let one pair of ice creams be some z.

So now z + z + 5 = 13

⇒ 2z + 5 = 13

⇒ 2z = 8

⇒ z = 8/2 = 4

Finally we have all the required values.

One pair of shoes = 10

So one shoe= 5

Similarly, one pair of ice creams = 4

One ice cream = 4/2= 2

We have one shoe + ( one child × one ice cream ).

We do the multiplication first following the DMAS rule.

Finally we have ( 5 × 2) + 5= 10 + 5= 15

The DMAS rule is attached below for your convenience.
