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

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.
