Answer 1

Answer:

Friends…!

Let the number be x

35% of a number is 12 less than 50 percent of that number, then what is the number

35% of x = 35/100×x = 0.35x

50% of x = 50/100 × x = 0.50x

0.35x + 12 = 0.50x

0.35x - 0.50x = —12

—0.15x = —12

x = 12/0.15

x = 80

Thus the number is 80

Answer the number is 80
