Which two signs and two numbers should be interchanged in the followin...
Given:
60 × 3 + 660 ÷ 6 – 20 = 290
Calculation:
By option Method:
Option 1: exchange 6 and 660, × and ÷
⇒ 60 ÷ 3 + 6 x 660 – 20 = 290
⇒ 20 + 3960 - 20 = 290 
⇒ 3960 ≠ 290
This is not correct the equation.
Option 2: exchange 20 and 6, + and -
⇒ 60 × 3 - 660 ÷ 20 + 6 = 290
⇒ 180 - 33 + 6 = 290
⇒ 153  ≠ 290
This is not correct the equation.
Option 3: exchange 20 and 60, + and × 
⇒ 20 + 3 x 660 ÷ 6 – 60 = 290
⇒ 20 + 330 -60 = 290
⇒ 290 = 290
This is correct the equation.
Option 4: exchange 20 and 660, + and ÷
⇒ 60 × 3 ÷ 20 + 6 – 660 = 290
⇒ 9 + 6 - 660 = 290
⇒ -645 ≠ 290
This is not correct the equation.
Hence, 'Option 3' is the correct answer.

Similar Airforce X Y / Indian Navy SSR Doubts

Direction: Read the following passage and answer the question that follows.Unfortunately, the reality hit me the next morning. I slept past the chirping of birds but was woken up by loud voices crossing my window every now and then. When I went to the kitchen to make myself some tea, a couple of tourists were peeping in through the glass door. Day trippers! The old-world charm of this village, with only 305 residents, was drowned by the callousness of visitors who only seemed to care about their photos and getting drunk, almost running over the locals in their rental cars, never realizing that they were intruding into someone’s sleepy neighborhood and life. My hosts assured me that the number of day trippers now was not nearly as bad as in the peak summer season, and joked about how the village residents, their homes and their kitchens must be curious, unfamiliar sights for tourists. If you’re on the same page, you’re probably thinking that an easy solution is that travel bloggers like me should never write about their “offbeat” finds. But as my social media followers often remind me, isn’t it part of my job to disclose the exact location of my stories and photos, so others can choose to experience my finds over ‘tourist traps’? I’ve dwelt on this dilemma for a long time. But walking on those cobblestoned streets in Istria (mostly at sunrise and late at night), it occurred to me that no, perhaps that isn’t the role a travel blogger is supposed to play. The way I see it now, my work as a travel blogger should inspire my readers to think of travel differently – to reconsider their travel choices, to seek local encounters, to carve out their own journey. It’s the reason I never have, and never will give you a three-day itinerary to “do” a destination. That’s not how I aspire for my readers to experience somewhere I’ve been and loved.Q. Which of the following is not an example of callousness of the day-trippers?
