when my age is 18 my sister is half of my age. At present, my age is 80. what is sister age?

$\large \bold {\underline {\underline \green {solution}}}$

thєn,

• mч αgє = 18 чєαrs

• sístєr αgє = 1/2 σf mч αgє

• sístєr αgє = 1/2×18= 9 чєαrs

prєsєnt ,

• mч αgє = 80 чєαrs

• sístєr's αgє = 1/2 чєαrs σf mч αgє
• sístєr's prєsєnt αgє = 1/2 × 80= 40 чєαrs

∴ sístєrs prєsєnt αgє ís 40 чєαrs whєn mч prєsєnt αgє ís 80 чєαrs.
