Here’s the current “equation” for Pakistan to qualify for the semi-final of the ongoing T20 World Cup scenario you’re asking about, expressed in simple terms and then as rough formulas.

1. Basic qualification conditions

  1. England must beat New Zealand in their last Super 8s game.
    • If New Zealand win or the match is washed out, Pakistan are effectively out.
  1. Pakistan must beat Sri Lanka in their last Super 8s match.
    • A normal, narrow win is not enough; it has to be a big margin because of net run rate (NRR).
  1. If those two results happen, Pakistan and New Zealand both finish on the same points (3) and the semi-final spot is decided by NRR , where New Zealand currently have a big advantage.

2. Practical “equation” – what Pakistan actually need

Different outlets give slightly different “headline numbers,” but they all say broadly the same thing: Pakistan need a huge win over Sri Lanka to jump New Zealand on NRR.

If Pakistan bat first vs Sri Lanka

Most analyses boil down to:

  • Pakistan must win by around 64–65 runs or more to go ahead of New Zealand on NRR.

You can think of it roughly as:

Margin condition (batting first):
Pakistan’s victory margin in runs ≥ 64–65

Some reports phrase it as “about 65–70 runs” because exact NRR depends on the final totals and overs, but ~65 runs is the key benchmark being quoted.

If Pakistan chase vs Sri Lanka

If Sri Lanka bat first and Pakistan chase, then the equation becomes about overs , not run margin.

Typical number being used:

  • Pakistan must chase the target in about 13 overs (13.0–13.1) to 13-something overs depending on the exact target.

One worked example given:

  • If Sri Lanka set 140 , Pakistan need to reach 141 in 13.0 overs to go past New Zealand on NRR.
  • If the target is 142 , then 142 in 13.1 overs can be enough;
  • For 143 , then 143 in 13.2 overs , and so on, with only tiny extra leeway.

You can express that in a rough “equation” like:

Let T = target to chase.
Pakistan must reach T in roughly 13 + f(T) overs, where f(T) is a tiny fraction (0.1, 0.2, etc.) that shifts with the exact target but always keeps the chase inside ~13-point-something overs.

In “plain talk” used by TV and news:

  • “Chase in 13 overs ” or
  • “Chase in around 13.1 overs ”

is the shorthand qualification equation for a typical T20 total.

3. Net Run Rate – why these numbers?

Net run rate is:

NRR=total runs scoredtotal overs faced−total runs concededtotal overs bowled\text{NRR}=\frac{\text{total runs scored}}{\text{total overs faced}}-\frac{\text{total runs conceded}}{\text{total overs bowled}}NRR=total overs facedtotal runs scored​−total overs bowledtotal runs conceded​

New Zealand currently sit around +1.390 , while Pakistan are roughly -0.46 , so Pakistan need a swing of nearly 1.85 NRR points in a single match.

That’s why:

  • A normal 10–20 run win or
  • A chase in 17–18 overs

does nothing; only a crushing win (huge margin or ultra-fast chase) changes the NRR enough.

4. One-line forum-style summary

If England beat New Zealand, Pakistan’s semi-final equation is brutal but clear: beat Sri Lanka by about 65 runs if batting first, or chase the target inside roughly 13 overs (13-point-something depending on the total) to jump New Zealand on NRR and reach the semis.
