1
What is the average cashless transactions of Oxygen, Buddy and FreeCharge wallet after demonetisation?
» Explain it
A
Total number of cashless transactions of Oxygen wallet after demonetisation
=   150% of 140
=   210

Similarly,  Buddy wallet
=   170% of 140
=   238

And FreeCharge wallet
=   120% of 320
=   384

 ∴   Reqd average = 210 + 238 + 384 3

 = 210 + 238 + 384 = 832 = 277.3 3 3

Hence, option A is  correct.

2
Cashless transactions before demonetisation in all the e-wallets is approximately what per cent of the cashless transactions in all the e-wallets after demonetisation?
» Explain it
C
Total number of transactions before demonetisation
=   650 + 320 + 280 + 140 + 140
=   1530

Total number of transactions after demonetisation
=   130% of 650 + 120% of 320 + 140% of 280 + 150% of 140 + 170% of 140
= 845 + 384 + 392 + 210 + 238  = 2069

 = 1530 × 100 2069

= 73.94 ≈ 74%

Hence, option C is correct.

3
What is the ratio of the number of cashless transactions of Freecharge wallet after demonetisation to that of the Oxygen wallet?
» Explain it
A
The total number of transactions of FreeCharge wallet after demonetisation
=   120% of 320
=   384

Similary, Oxygen wallet
=   150% of 140
=   210

 ∴   Reqd ratio = 384 210
=   64 : 35

Hence, option A is correct.

=   69

Hence, option D is correct.
