Barry earns £1300 a month . He spends 30% of this money on rent and 12% on bills how much of the £1300 has he left

754

Step-by-step explanation:

barry earns 1300.

he spends 30% of the money

= 30% X 1300

= 30/100 X 1300

= 30 X 13 = 390

so, he spends 39 on rent.

he spends 12% of 1300

= 12/100 X 1300

= 12 X 13

= 156

so he spends 156 on bill.

now he spends total (156 + 390 ) = 546 on rent and bill.

so he was left with = (1300 - 546) = 754

here is another method

he spends total (30% + 12%) = 42% on rent and bill.

that means he spends on bill and rent = 42% of 1300

= 42/100 X 1300

= 42 X 13

=546

hence, he is left with = (1300 - 546) = 754
