Ism a number tell my question
Take me seven times over and add a fifly
To reach a triple century you need forty

Answer 1

Answer:

30

Step-by-step explanation:

triple century means 300

for that we have to add 40. so 300 -40 = 260

to reach 260 we are asked to add 50. so, 260-50 = 210

the number said take me seven times over . so, 210/7 = 30

in steps:

let the no. be x

300= 7x+50+40

300-50-40 = 7x

300 - 90 = 7x

210= 7x

210/7 = x

30 = x
