Solutions

Ans. 1. 

Number of members in Kshatriya family= 480/5×12 = 8
Total members of all families= 4+8+5+7+8+10=42
⇒ number obtained= 42×8=336
sum of digits= 3+3+6=12.

Ans. 2.

Surplus of wheat by
⇒ Brahmin= 480-(12×10×4) =0
⇒ Kshatriya= 672-(12×7×8) = 672-672=0
⇒ Vaishya = 450-(12×7×5) = 450- 420=30
⇒ Shudra= 504-(12×6×7) = 504-505 = 0
⇒ Dev = 750-(12×6.5×8) = 750-624=126
⇒ Danav = 420-(12×3.5×10) = 420-420=0
Total surplus = 126+30= 156

Ans. 3.

 Surplus of Rice by
⇒ Brahmin= 520-(12×9×4) = 88
⇒ Kshatriya= Zero
⇒ Vaishya = 800-(12×10×5) = 200
⇒ Shudra= 210-(12×4×7) = Negative Surplus
⇒ Dev = 550-(12×5×8) = 550-480=70
⇒ Danav = 420-(12×3.5×10) = 420-420=0
therefore it’s quite evident that only two families viz. Vaishya & Dev have surplus more than 100kg if taken rice and wheat together.

Ans. 4.

The given ratio is;
Rice:wheat:pulse = 22:30:5.
Look in the table that for a particular family which crop is less comparatively than other families
For Brahmin family, 520/22, 480/30, 80/5= the min of three will be 16 so (22+30+5)×16 kg khichadi can be made.
For Kshatriya family, 480/22, 672/30, 100/5 = the min of three will be 20 so 57×20 kg khichadi can be formed.
Proceed like this with all family, and we will find that Dev family will be able to make maximum quantity of khichadi.

Ans. 5.

By question 3, we know that Shudra family has a negative surplus of rice so it simply means that they don’t have enough to meet their yearly consumptions.

Ans. 6.

The Vaishya family has 30kg surplus of wheat and relative consumption is 60kg so they need to reduce their consumption by 60-30=30kg/year
so, per head/ month reduction in wheat consumption = 30/12×5 = 0.5Kg

Ans. 7.

Dev family consumption= = 96×11.5
Danav family consumption = 12×10× (7+3.5) = 120×10.5
Therefore required ratio = 96×11.5/120×10.5 = 92:105

Ans. 8.

Surplus production of Pulse by
⇒ Brahmin= 80-(12×4×1.5) = 8
⇒ Kshatriya= 100-(12×8×1) = 4
⇒ Dev= 125-(12×8×1.3) =125-124.8= 0.2
⇒ Danav = 110-(12×10×0.8) = 110-96= 14

Ans. 9.

The Shudra family doesn’t have surplus production, so data is inconsistent.

Ans. 10.

Total production of three crops by
⇒ Brahmin= 520+480+80= 1080
⇒ Kshatriya= 480+672+100= 1252
⇒ Vaishya = 800+450+120= 1370
⇒ Shudra= 210+504+75 = 789
⇒ Dev = 550+750+125= 1425
⇒ Danav = 420+880+110 =1410
So, Danav has higher production of three crops taken together.

Ans. 11.

Total production of rice by all families = 3440kg
total production of wheat by all families = 3276kg.
Therefore, difference= 3440-3276=164.
