Question

if 9=10 ,8=18, ,7=24, 5=30., then 3=?

Answer 1

if 9=10 , 8=18 , 7=24, 5=30 ,
Then,
3=36,

Answer 2

Answer:

The value of $3= 28.$

Step-by-step explanation:

Given:

Let, $9=10, 8=18, 7=24, 5=30$

To find:

value of $3 = ?$

Step 1

Let, the values be calculated as follows,

a. $9 = 10$

$9*1 +1 = 10$

b. $8 = 18$

$8*2 + 2=18$

c. $7= 24$

$7*3+ 3 =24$

and

d. $5= 30$

$5*5 +5= 30$

then we have to find the value of $3=?$

we see the number is multiplied and again added by the same number in reverse orders,

$9-1, 8-2, 7-3, 6-4, 5-5, 4-6, 3-7, 2-8, 1-9$

Hence, We can calculate the value of $3.$

Step 2

e. To find the value of $3$, we get

$3=?$

$3*7 +7= 28$

here we multiply and add $7.$

Hence the value of $3= 28.$
