Question

The value of 8 2/5 / 3 1/2 of 7 1/5 - (7 1/5 - 2 7/10) / (1 7/8 / 1 1/3 of 3/16) is ?
a -2/3 b 3/5 c 7/10 d -4/15

Answer 1

Given :- The value of 8 2/5 / 3 1/2 of 7 1/5 - (7 1/5 - 2 7/10) / (1 7/8 / 1 1/3 of 3/16) is ?

a -2/3

b 3/5

c 7/10

d -4/15

Solution :-

→ {8(2/5)/3(1/2) of 7(1/5)} - {7(1/5) - 2(7/10)} / {(1(7/8) /1(1/3) of 3/16)}

writing all Mixed fraction as improper fraction ,

→ {(42/5) / (7/2) of (36/5)} - {(36/5) - (27/10)} / {(15/8) / (4/3) of (3/16)}

Solving "of" now,

→ {(42/5) / (126/5)} - {(36/5) - (27/10)} / {(15/8) / (1/4)}

solving division now,

→ {(42/5) * (5/126)} - {(72 - 27)/10} / {(15/8) * 4}

→ (1/3) - {(45/10) / (15/2)}

→ (1/3) - {(45/10) * (2/15)

→ (1/3) - (3/5)

taking LCM of denominators ,

→ (5 - 9)/15

→ (-4/15) (Option D) (Ans.)
