Answer:

27 MINUTES

Step-by-step explanation:

TIME TAKEN BY ALISHA=36 MINUTES

GIVEN, ALISHA WORKS 3 TIMES FASTER THAN SITA

SO,

TIME TAKEN BY SITA=36*3

                                   =108 MINUTES

TIME TAKEN WHEN ALISHA AND SITA WORKS TOGETHER=(1/36)+(1/108)

LCM OF 36 AND 108=108

(1/36) + (1/108)

(3+1)/108

4/108

=1/27

THEREFORE,27 MINUTES
