Question

Kitty gave her friends clues about a number she was thinking ofshe told them that when her number is tripled and added to 25 the result is 925 what is the number Katie was thinking of

Answer 1

let the number she is thinking about be X .
then, tripled = 3x
Number kitty is thinking of = 3x + 25 = 925
=> 3x= 925-25
=> 3x = 900
=> x. = 900/3
=> x = 300
3x = 3×300
=> 900
hence, the required number is 900.

Answer 2

let the number be 3x
according to the question;-
=> 3x + 25 = 925
=> 3x = 925-25
=> 3x = 900
=> x = 900/3
=> x = 300

Hence the required number is 300
