Answer: Option A. -> ₹ 800, ₹ 1000
:
A
The ratio of their ages is 12: 15 or 4 : 5.
So, the money has to be divided in the ratio 4 : 5.
Let theshares be 4x and 5x respectively.
Now, 4x+5x=9x
Thus, 9x=1800⟹x=200
Hence, the sharefor the 12 year old son is
4x= 4×200= ₹ 800
The sharefor the 15year old son is
5x= 5×200= ₹ 1000

Answer: Option C. -> 50 km
:
C
The bus travels 500 km with 70 litres of petrol.
Hence, with one litre it can travel
50070km.
∴ with7 litres, the bus will cover a distance of
50070×7=50km

Each Option: 1 Mark
(a) 2hrs=60×2=120 minutes (1 hr = 60 minute)
Ratio of 20 minutes to 2 hrs = 20:120 =1:6
[ Remember that for taking ratio unit of both quantitiesshould be same ]
(b)5:4::125:x⇒54=125x
⇒54=125x
⇒45=x125
⇒x=125×45=25×4
⇒x=100

Steps: 2 Marks
Answer: 1 Mark
Number of runs made by Anish in 6 overs
= 42
Number of runs made by Anup in 7 overs
= 63
Number of runs made by Anish in 1 overs
= 426 = 7
Number of runs made by Anup in 1 overs
= 637 = 9
Therefore, Anup made more runs per over.
Ratio of their runs made
AnishAnup=4263=23⇒2:3
