Marks: +1, -0

What is the value of

1.\ov 34+ 4. 1\ov2

?

$133/90$
$371/90$
$5 219/990$
$5 461/990$

Solution:

(d)

∴1 . \ov { 34 } = \ { 134 - 1 } /{ 99 } = { 133 }/ { 99 }

and

4.1 \ov { 2 } = { 412 - 41 }/ { 90 } = { 371 } /{ 90 }

∴1 . \ov { 34 } + 4.1 \ov { 2 } = \ { 133 }/ { 99 } + { 371 } /{ 90 }

= { 1330 + 4081 } /{ 990 }

= { 5411 }/ { 990 } = 5 { 461 }/{ 990 }
