What should be added to each term of the ratio 7 : 13 so that it becomes 2 : 3?
अनुपात 7 : 13 के प्रत्येक पद में क्या जोड़ा जाए ताकि नया अनुपात 2 : 3 हो जाए?
Detailed Solution & Logic
Correct Answer:
5
समाधान:
मान लेते हैं कि प्रत्येक पद में $x$ जोड़ा जाता है।
तो नया अनुपात होगा:
$(7+x):(13+x)=2:3$
इसलिए,
$3(7+x)=2(13+x)$
$21+3x=26+2x$
$x=5$
अतः प्रत्येक पद में 5 जोड़ा जाना चाहिए।
उत्तर: 5
