UPSC Prelims 2018 GS Paper I · Q29 of 100 Geography medium

Among the following cities, which one lies on a longitude closest to that of Delhi ?

  1. (a) Bengaluru ✓ UPSC's answer
  2. (b) Hyderabad
  3. (c) Nagpur
  4. (d) Pune

Why the answer is (a)

• Delhi lies at about 77.2° E longitude.

• Bengaluru is at about 77.6° E — barely half a degree east of Delhi, so it lies almost due south — option (a).

• Hyderabad is at about 78.5° E, Nagpur at about 79.1° E and Pune at about 73.9° E, all farther from Delhi's meridian.

• Hence option (a).

Why the other options are wrong

Hyderabad (78.5° E) is over a degree east of Delhi.
(c) Nagpur
Nagpur (79.1° E) is nearly two degrees east.
(d) Pune
Pune (73.9° E) is over three degrees west.
