Apple just secretly added Starlink satellite support to iPhones through iOS 18.3.

One of the biggest potential winners? Mode Mobile.

Mode’s EarnPhone already reaches 490M+ users that have earned over $1B, and that’s before global satellite coverage. With SpaceX eliminating "dead zones," Mode's earning technology can now reach billions more in unbanked and rural populations worldwide.

Their global expansion is perfectly timed, and investors like you still have a chance to invest in their pre-IPO offering at $0.52/share.

With their recent 32,481% revenue growth and newly reserved Nasdaq ticker, Mode is one step closer to a potential IPO.

Please read the offering circular and related risks at invest.modemobile.com. This is a paid advertisement for Mode Mobile’s Regulation A+ Offering.

Mode Mobile recently received their ticker reservation with Nasdaq ($MODE), indicating an intent to IPO in the next 24 months. An intent to IPO is no guarantee that an actual IPO will occur.

The Deloitte rankings are based on submitted applications and public company database research, with winners selected based on their fiscal-year revenue growth percentage over a three-year period.

✅ Answers & Explanations

❝

Set 1

Total posts = 12
Available persons = 15

Girls available:
M.Com girl, M.A girl, B.Com girl, B.A girl

Key restrictions:

Manager can be M.Com / M.B.A / M.A. A girl can be Manager alone.

Marketing Executives must be M.B.A. Since all 4 M.B.A candidates are boys, all Marketing Executives will be boys.

Finance Personnel must be M.Com / M.B.A. The only eligible girl here is the M.Com girl. Since Finance has 2 posts, if she is selected, another girl must be selected in Finance, which is impossible. So M.Com girl cannot be in Finance.

Accountants must be B.Com / M.Com. The eligible girls are M.Com girl and B.Com girl. So if girls are selected as Accountants, both must be selected together.

Clerks must be B.Com / B.A. The eligible girls are B.Com girl and B.A girl. So if girls are selected as Clerks, both must be selected together.

Solutions

Question 1

12 people are needed, but only 11 boys are available. So at least one girl must be sent.

Answer: d) No girl is sent to the branch.

Question 2

If none of the B.A boys is sent, then 2 persons are already excluded. Since only 3 out of 15 can be excluded, only one more person can be left out.

All 4 girls cannot be selected together because the B.Com girl would be needed both as Accountant and Clerk. Hence the false statement is that all girls must be sent.

Answer: b) Only (2)

Question 3

All 4 girls cannot be selected together due to cadre restrictions. So not more than three girls can be sent.

Answer: c) Only (1)

Question 4

Marketing Executives must be M.B.A. If none of the 4 M.B.A boys is sent, then all 3 Marketing Executive posts require new hires.

Answer: c) Three
