If 24 + 35 = 28; 15 + 42 = 24; 84 + 57 = 48 then 69 + 37 = ?

Question

Q. In the following question, three statements of numbers following the some rule are given. Find the rule and accordingly find the value of the number.

If

24 + 35 = 28; 15 + 42 = 24; 84 + 57 = 48,

then

69 + 37 = ?

Answer 1

The rule is : Add up the digits on LHS and double the sum to get RHS

24+35=(2+4+3+5)×2=14×2=2824+35=(2+4+3+5)×2=14×2=28 etc

∴(69+37)=(6+9+3+7)×2=25×2=50∴(69+37)=(6+9+3+7)×2=25×2=50

If 24 + 35 = 28; 15 + 42 = 24; 84 + 57 = 48 then 69 + 37 = ?

The correct option is D 50The rule is : Add up the digits on LHS and double the sum to get RHS24+35=(2+4+3+5)×2=14×2=2824+35=(2+4+3+5)×2=14×2=28 etc∴(69+37)=(6+9+3+7)×2=25×2=50∴(69+37)=(6+9+3+7)×2=25×2=50

The correct option is D 50
The rule is : Add up the digits on LHS and double the sum to get RHS
24+35=(2+4+3+5)×2=14×2=28 etc
∴(69+37)=(6+9+3+7)×2=25×2=50
