30 : 36 is the number pair/group which is different from others [ The correct option is 2. 30 : 36 ]

Given :

The number pair/group 40 : 50 , 30 : 36 , 8 : 10 , 28 : 35

To find :

The number pair/group which is different from others

1. 40 : 50

2. 30 : 36

3. 8 : 10

4. 28 : 35

Solution :

Step 1 of 2 :

Write down the given number pair/group

Here the given number pair/group are 40 : 50 , 30 : 36 , 8 : 10 , 28 : 35

Step 2 of 2 :

Find the number pair/group which is different from others

For the pair 40 : 50

40 : 50

\displaystyle \sf   =  \frac{40}{50}

\displaystyle \sf   =  \frac{40 \div 10}{50 \div 10}

\displaystyle \sf   =  \frac{4}{5}

\displaystyle \sf   = 4 : 5

For the pair 30 : 36

30 : 36

\displaystyle \sf   =  \frac{30}{36}

\displaystyle \sf   =  \frac{30 \div 6}{36 \div 6}

\displaystyle \sf   =  \frac{5}{6}

\displaystyle \sf   = 5 : 6

For the pair 8 : 10

8 : 10

\displaystyle \sf   =  \frac{8}{10}

\displaystyle \sf   =  \frac{8 \div 2}{10 \div 2}

\displaystyle \sf   =  \frac{4}{5}

\displaystyle \sf   = 4 : 5

For the pair 28 : 35

28 : 35

\displaystyle \sf   =  \frac{28}{35}

\displaystyle \sf   =  \frac{28 \div 7}{35 \div 7}

\displaystyle \sf   =  \frac{4}{5}

\displaystyle \sf   = 4 : 5

We observe that every ratio except 30 : 36 is equivalent to 4 : 5

∴ 30 : 36 is the number pair/group which is different from others

Hence the correct option is 2. 30 : 36
