Question

(ii) The ratio of the number of boys to the number of girls in a school of 560 pupils is
5: 3. If 10 new boys are admitted, find how many new girls may be admitted so
that the ratio of the number of boys to the number of girls may change to 3:2.​

Answer 1

Answer: 30 girls

Step-by-step explanation: first find the number of boys and girls when i did that the boys was 350 while the girls was 210

then i added 10 to the boys like the question stated

so i found a number that when i divide it by 360 you would get 3 or 30 which was 12 or 120

then i multiplied 120 times 2 which gave me 240

therefore u would do 240 minus 210 equals to 30 therefore the answer is 30
