Aap apnay friend ko tahain tay wo apni age dil main soch lay,
Phir us main 95 + karay, and jo jawab aey us main say jo left side par pahla hindsa hay us ko mita day, like ( AGAR 120 banay to 1 ko mita dain , yani sirf 20 rahnay day )
Phir 20 main 1 + karay ( yani 20+1= 21 )
Aur jo jawab aey wo aap ko bata day
Phir aap dil hi dil US JAWAB main 4 + kar kay friend ko bata dain , wohi aap kay friend ti age ho gi
“ Like agar friend ki age 16 hay to wo us main 95 + karay ga, and answer 111 aey ga phir wo us main say 1 mita day ga and sirf 11 bach jaey ga, aur us main 1 + karay ga to jawab aey ga 12.
Ab aap ta friend aap to 12 batay ga to aap dil hi dil main us main 4 + kar kay ( 12+4=16) us ko bata dain gaey kay us ki age 16 hay
