Onika gives money to a charity directly from her wages, before tax. One sixth of her monthly earnings goes to the charity, then one fifth of what's left gets deducted as tax. How much money goes to charity and on tax, and how much is left, if she earns £2400?

Answer 1

Onika gives 1/6 of her earnings to the charity before tax, which is (1/6) x £2400 = £<<1/6*2400=400>>400.
The amount left after giving £400 to charity is £2400 - £400 = £<<2400-400=2000>>2000.
Then, 1/5 of what's left is deducted as tax, which is (1/5) x £2000 = £<<1/5*2000=400>>400.
The total amount deducted for tax and charity is therefore £400 + £400 = £<<400+400=800>>800.
The amount left after the deductions is £2400 - £800 = £<<2400-800=1600>>1600. Answer: \boxed{£400} to charity, \boxed{£400} on tax, and \boxed{£1600} left.
