## 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.
