91) Which of the following is a non-terminating recurring decimal?
క్రింది వాటిలో అంతం కాని ఆవర్తితమయ్యే దశాంశం ఏది?

A) $\frac{5}{8}$
B) $\frac{3}{7}$
C) $\frac{14}{35}$
D) $\frac{13}{16}$

View Answer

B) $\frac{3}{7}$

Explanation:A rational number gives a terminating decimal only if the denominator (in lowest form) has prime factors 2 and/or 5 only.
1) 5/8 = 5/ $(2^3)$ → terminating
2) 3/7 → denominator has 7 → non-terminating recurring ✔
3) 14/35 = 2/5 → terminating
4) 13/16 = 13/ $(2^4)$ → terminating

92) If 3600 = $2^{x} \times 3^{y} \times 5^{z},\ \text{then } \frac{xy + yz + zx}{x + y + 2z}$ =
3600 = $2^{x} \times 3^{y} \times 5^{z} \text{ అయితే } \frac{xy + yz + zx}{x + y + 2z}$ =

A) 3
B) 1
C) 2
D) 4

View Answer

C) 2

Explanation:3600 = 36 × 100
= $(2^2 × 3^2)(2^2 × 5^2)$
So, x = 4, y = 2, z = 2
(xy + yz + zx) / (x + y + 2z)
= (4×2 + 2×2 + 4×2) / (4 + 2 + 4)
= (8 + 4 + 8) / 10
= 20 / 10
= 2

93) Five years ago sum of the ages of Anitha and Sunitha is 42 years. Anitha is elder than Sunitha by 4 years. The ratio of present ages of Anitha and Sunitha is
ఐదు సంవత్సరాల క్రితం అనిత మరియు సునితల వయస్సుల మొత్తము 42 సంవత్సరాలు. సునిత కంటే అనిత 4 సంవత్సరాలు పెద్దది. అనిత మరియు సునితల ప్రస్తుత వయస్సుల నిష్పత్తి

A) 6:5
B) 8:7
C) 4:3
D) 7:6

View Answer

D) 7:6

Explanation:Let Sunitha’s age 5 years ago be x.
Then Anitha’s age = x + 4
x + (x + 4) = 42
2x = 38 → x = 19
Present ages:
Sunitha = 24 years
Anitha = 28 years
Ratio = 28 : 24 = 7 : 6

94) If cost of 5 $\left( \frac{1}{4} \right)$ dozens of apples is ₹1386, then the cost of 9 apples is
5 $\left( \frac{1}{4} \right)$ డజన్ల ఆపిల్ పండ్ల ధర ₹1386 అయితే, 9 ఆపిల్ పండ్ల ధర

A) ₹198
B) ₹225
C) ₹156
D) ₹204

View Answer

A) ₹198

Explanation:5¼ dozens = (21/4) × 12 = 63 apples
Cost of 63 apples = ₹1386
Cost of 1 apple = 1386 ÷ 63 = ₹22
Cost of 9 apples = 22 × 9 = ₹198

95) $\frac{(0.2)^2 + (0.3)^2 + (0.4)^2}{(0.5)^2} =$

A) 1.60
B) 1.24
C) 1.16
D) 1.08

View Answer

C) 1.16

Explanation: $(0.2)^2 + (0.3)^2 + (0.4)^2$
= 0.04 + 0.09 + 0.16
= 0.29
$(0.5)^2 = 0.25$
0.29 ÷ 0.25 = 1.16
