Options

• `2/7`

• `1/14`

• `2/3`

• `4/21`

Answer 1

`4/5` of 5 kg apples were used on Monday. The next day `1/3` of what was left was used. Weight (in kg) of apples left now is `underlinebb(2/3)`.

Explanation:

Apples used on Monday = `4/5` of 5 = `4/5 xx 5`

= 4 kg

Remaining apples = 5 – 4

= 1 kg

Apples used next day = `1/3` of remaining apples

= `1/3 xx 1` kg

= `1/3` kg

So, weight of apples left now

= Total apples – Apples used on Monday – Apples used next day

= `(5 - 4 - 1/3)`

= `(15 - 12 - 1)/2`  ...[Taking LCM]

= `2/3` kg
