43. Question 15
• A total of PHP 75,000.00 is deposited into two simple
interest accounts. In one account the annual simple
interest rate is 5% and in the second account the
annual simple interest rate is 7%. The amount of
interest earned for 1 year was Php 4,050.00 . how
much was invested in each?
A. At 5 %= Php 60,000.00; at 7%= Php 15,000.00
B. At 5 %= Php 50,000.00; at 7%= Php 25,000.00

D. At 5 %= Php 15,000.00; at 7%= Php 60,000.00
44. • Let x be the amount deposited in 5% account.
• Then 75000 – x is the amount deposited in the 7% account.
• Let I be the combined interest gained from the two accounts.
• Using the formula I = PRT
• where I = interest gained
• P = principal amount
• R = interest rate
• T = time in years
• There are two interests here so I = I1 + I2, where I1 is the interest
from the 5% account and I2 is from the 7% account. Since we are
dealing with a 1 year term, we can ignore the T here.
• I = x(0.05) + (75000-x)(0.07)
• 4050 = 0.05x + 5250 – 0.07x
• -0.02x = -1200
• x = 60000
• thus 60000 was invested at 5% while 15000 was at 7%

300. Question 112
• the set G= {a,e,b,c} forms a group with the
operator O. The group table is given by:
• Find the inverse of c.
A. c C. a
B. e D. b
• Answer is based on the table, although the
topmost row should probably be e, a, b, c.
301. Question 113
The trace of the square matrix A, to (A), is the
sum of its diagonal elements if
Find tr (A)+tr(B)
A. 19 C. 21
B. 26 D. 24
302. Question 113
The trace of the square matrix A, to (A), is the sum
of its diagonal elements if
Find tr (A)+tr(B)
A. 19 C. 21
B. 26 D. 24
We just get the sum of the main diagonal if we want the
trace.

A. Subgroups for a partition of a group
B. The intersection of two subgroups is empty
C. The union of two subgroups is also a group
D. The intersection of two subgroups is also a group
305. Question 115
Find the x and y intercepts of the following: y=
2x2-3x-2
A. (0,-2),(2,0),(-1/2,0) C. (2,0),(2,0),(-1/2,0)
B.(0,2),(1,0),(-1/2,0) D.(0,-2),(2,0),(-2.0)
306. • y= 2x2-3x-2
• Let y = 0
• 0 = 2x2-3x-2
• (2x + 1)(x – 2) = 0
• x = -1/2 and x = 2
• Let x = 0 in y= 2x2-3x-2
• y = -2
• Thus intercepts are (0, -2), (-1/2, 0) and (2, 0)
•

• Find the determinant of the co-factor of q33 of
– 30 C. 13
– 23 D. -13
309. • Determinants of q33
• = q11 x q22 – q21 x q12
• = 2(1) – 5(3)
• = 2 – 15
• = -13
