The given table represents the exports (in Rs.crores) of four items A, B, C and D over a period of six years. Study the table and answer the question that follows.
| Item→ | A | B | C | D |
| Year↓ | ||||
| 2010 | 240 | 128 | 180 | 214 |
| 2011 | 250 | 134 | 244 | 282 |
| 2012 | 225 | 138 | 230 | 247 |
| 2013 | 370 | 169 | 340 | 224 |
| 2014 | 425 | 182 | 300 | 309 |
| 2015 | 400 | 209 | 306 | 275 |
The total exports of item A from 2012 to 2014 is what percentage less than the total exports of all the four items in 2015? (Correct to one decimal place)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 14.3%
The total exports of A from 2012 to 2014 = 225 + 370 + 425 = 1020
The total exports in 2015 = 400 + 209 + 306 + 275 = 1190
The required percentage will be = [(1190 - 1020) / 1190] × 100
⇒ [170 / 1190] × 100
⇒ 14.28% or 14.3%
