What is the next value 1I2L3F4
zmey [24]
The given terms can be divided into two sections. First section is for the numbers and the second one for the letters.

1st section:    1, 2, 3, and 4
2nd section:    I, L, F


I is the 9th letter in the alphabet, L is the 12th letter, and F is the 6th letter in the alphabet. 

The pattern observed:
                    I to L:    12 - 9 = 3
                    L to F:    6 - 12 = -6

Next letter should be +9. This means that the letter should be 9 places higher than F. The letter should be O which is the 15th letter.

What is the yield on a corporate bond with a $1000
White raven [17]

The yield on the corporate bond of a face value of $1000 is 7.77%.

What is the percentage discount?

The percentage discount is the discount given on a product as compared to the given discount on 100 rupees.

Given, the face value of the bond is $1000.

Discounted price of the bond is $900.

Therefore, the fixed interest on the bond for that period will be

= $1000 × 7/100 = $70.

Now, the yield on that corporate  bond = 70 × 100/900 % = 7.77% .

Hence, the yield on the corporate bond of a face value of $1000 is 7.77%.
