Answer 1

HEY MATE,

SUSAN CAN TYPE 20 PAGES IN 10 MIN

SO SHE CAN TYPE 20 x 6 IN 10 x 6 MIN i.e. 60 MIN

i.e. SHE CAN TYPE 120 PAGES

MARY CAN TYPE 5 PAGES IN 10 MIN

SO SHE CAN TYPE 5 x 6 PAGES IN 10 x 6 MIN i.e. 60 MIN

i.e. SHE CAN TYPE 30 PAGES

120 +30 =150

THUS, BOTH OF THEM CAN TYPE 150 PAGES IN 60 MIN
