Question

If 25% of a number is less than 18% of 650 by 19 ,find the number​

Answer 1

Answer:

Step-by-step explanation:

• 25% of a number = (25÷100) of X
• let X be the number

according to the question 18% of 650 is less than 25%of X , that is (18÷100)×650 - (25÷100) × X = 19

• on simplification,

• 117-(X/4) = 19                          (25÷100=1/4)
• moving 117 to RHS,

        -X/4=19-117

                =-98

         cancelling (- )on either side

•  X= 98×4=392

                                         THE ANSWER IS 392
