Question

On her birthday Gayatri distributed 70% of the
sweets in her own class. She then went to her
friends in other sections and distributed 50% of the
remaining sweets. After distributing another
20 sweets among her teachers, she was still left
with 10 sweets. What was the total number of
sweets that Gayatri brought to the school?​

Answer 1

Answer:

200 sweets

Step-by-step explanation:

let gayatri has x sweets

after distributing 70 % she has 30 % sweets

= 30x/100

then she distributed 50 %of 30x/100

= 50×30x/100×100

15x/100

after distributing 50% of 30x/100

she 50 % remain = 20+10 = 30 .

so

15x/100 = 30

x = 30 ×100/15

x= 200 sweets
