A) 12 p.m. on Wednesday | B) 2 p.m. on Thursday |

C) 3 p.m. on Thursday | D) 2 p.m. on Wednesday |

Explanation:

Time from 12 p.m. on Tuesday to 2 p.m. on the following Tuesday = 7 days 2 hours.

= 170 hours.

The watch gains = (2 + 4 x 4/5) min

= 34/5 min. in 170 hrs.

Now, 34/5 min are gained in 170 hrs.

Then, 2 min are gained in (170 x 5/34 x 2) hrs.

Watch is correct after 2 days 2 hrs after 12 p.m. on Tuesday, i.e., it will be correct at 2 p.m. on Thursday.

X = 27

So, required percentage of benzene = 27 %

A) 541 times | B) 540 times |

C) 450 times | D) 275 times |

Siren sounds for every 5 seconds.

In 2700 seconds = 540 times.

The count start after the first sound, the Siren will sound 541 times in ¾ of an hour.
