Paraphin [41]

Answer:

C. 350

Step-by-step explanation:

A sample of 50 different coloured balls are removed from total golf balls made.

Out of these 50 coloured balls, 8 balls are pink

Now, to calculate the total number of golf balls made,

we can use the concept of proportion

\frac{number of pink colored balls in sample}{total pink colored balls made} = \frac{number of golf balls taken out as a sample}{ total number of golf balls made}

\frac{8}{56} = \frac{50}{total golf balls made}

total golf balls made = \frac{50\times56}{8}

total golf balls made = 350

Anastasy [175]

Answer:

UBL Bank

The result of this decrease in the reserve requirement in the balance sheet is reflected on the total amount of money created by UBL Bank increasing from PKR 46,000 million to PKR 57,500 million.

Step-by-step explanation:

Current transaction deposits on balance = PKR 4,600 million

Reserve requirement = 10 percent of transaction deposits

This implies that UBL Bank can create more money up to (4,600/0.1) million = PKR 46,000 million

If the State Bank of Pakistan decreases the reserve requirement to 8 percent, the money creation ability of UBL Bank will increase to (4,600/0.08) million = PKR 57,500 million

The effect of this change on its balance sheet is PKR 11,500 million.  This implies that UBL Bank's ability to create money is increased by PKR 11,500 million.
