Question : 1
4 years hence, the ratio of ages A and B will be 5 : 7 and 6 years hence, the ratio of ages will be 11 : 15, then nd their present ages.
a) 20 years, 26 years
b) 16 years, 24 years
c) 18 years, 28 years
d) 12 years, 18 years
e) None of these
Answer »Answer: (b)
Let the present ages of A and B be a years and b years, then
According to question
$\text"a+4"/5=\text"b+4"/7$
⇒ 7a – 5b = –8 …. (i)
And
$\text"a+6"/11=\text"b+6"/15$
⇒ 15a – 11b = –24 …. (ii)
On solving equations (i) and (ii), we get
a = 16 and b = 24
Hence, the ages of A and B will be 16 years and 24 years respectively.
Question : 2
Running at the speed of 3 km/hr, a person reaches his destination 10 minutes later than usual time. if he increases his speed by 1 km/hr, he reaches his destination 15 min earlier. nd the distance to his destination.

b) 12 km
c) 5 km
d) 4 km
e) None of these
Answer »Answer: (c)
Let the distance to his destination be d km, then
According to question we get,
$d/3$ – $d/(3+1) = \text"10+15"/60$
⇒$d/3$ – $d/4 = 5/12$
⇒$d/12 = 5/12$
⇒ d = 5
Hence, the distance to his destination = d = 5 km
Question : 3
A person invests a certain amount on simple interest. After 8 years he gets 16% interest. If he invests the same sum for 4 years, then he gets Rs. 9600 as interest, then the sum is

Question : 5
? × 350.01 ÷ 3.992 = 983 ÷ 14.001
a) 1.2
b) 1.8
c) 2.8
d) 3.2
e) 4
Answer »Answer: (d)
? × 350.01 ÷ 3.992 = 983 ÷ 14.001
After approximation, we get
? × 350 ÷ 16 = 980 ÷ 14
⇒ ? × 350 ÷ 16 = 70
⇒ ? = (70 × 16) ÷ 350 = 3.2
Question : 6
(1110.02 + 89.81) ÷ ? – $√{15}$ = 15.98
