One year ago, the ratio of Gaurav' and Sachin's age was 6 : 7 respectively Four years hence , this raio would become 7 : 8. How old is Sachin ? | [
"37 years",
"36 years",
"34 years",
"38 years"
] | B | Explanation :
Sol Let Gaurav's and Sachins ages one year ago be 6xand7x6xand7x 7ears respectively . Then
Gaurav's age 4 years hence = (6x+1) +4=(6x+5)(6x+1) +4=(6x+5) years
Sachin's age 4 years hence = (7x+1)+4=(7x+5)(7x+1)+4=(7x+5) years.
6X+5 / 7X+5 =7/8
⇔ 8(6x+5)= 7(7x+5)

P is able to do a piece of work in 15 days and Q can do the same work in 20 days. If they can work together for 4 days, what is the fraction of work left? | [
"7/15",
"8/15",
"None of these",
"1/15"
] | B | Explanation:
P's 1-day work = 1/15
Q's 1-day work = 1/20
Work done by (P + Q) in 1 day = 1/15 + 1/20 = 7/60.
Work done by them in 4 days = (7/60) * 4 = 7/15.
Work left = 1 - (7/15) = 8/15.

] | A | 8:00 am so 6 hours later is 2:00 pm
In six hours, Robert will have driven 6*60 = 360 miles
In six hours, Alive will have driven 6*80 = 480 miles
So Robert needs 480-360 = 120 miles do catch Alice up.
So at 60 mph, he will need 2 hours
2:00 pm + 2 hours = 4:00 pm

"20 metres",
"14 metres",
"12metres",
"16 metres"
] | A | Explanation:
length 115% of breadth.
length×breadth =460 m2
⇒ 115% of breadth×breadth =460 m2
⇒ 115/100×breadth×breadth =460 m2
⇒ breadth×breadth =400 m2
⇒ breadth =20 m

The first photo shoot takes 3 minutes long and then the following shoots are taken at a rate of 21 seconds/shoot as the model is already at the scene. What is the maximum number of photo shoots taken in 10 minutes ? | [
"21",
"15",
"14",
"16"
