Given:

The ratio of A and B's capital = 5 ∶ 6 

After 4 months, A withdraws 1/5 of his capital, while B increases his capital by \(33 \frac{1}{3}\)%

Total annual profit = Rs. 6.3 lakhs 

Concept used:

Divide the profit according to ratio of investment 

Calculations:

Let money invests by A and B be 5x and 6x respectively 

Total money invests by A in first 4 months = 5x × 4 = 20x 

Total money invests by B in first 4 months = 6x × 4 = 24x 

According to the question,

After 4 months money invests by A = 5x × 4/5 = 4x 

After 4 months money invest by B = 6x × (100 + 100/300)

⇒ 6x × 4/3 = 8x 

Total money invests by A in last 8 months = 4x × 8 = 32x

Total money invests by B in last 8 months = 8x × 8 = 64x

Total money invests by A in a year = 20x + 32x = 52x 

Total money invests by B in a year = 24x + 64x = 88x 

Ratio of money invests by A and B = 52x ∶ 88x 

⇒ 13 ∶ 22 

B's profit = (6,30,000/35) × 22 = 3,96,000

∴ Share of B is 3.96 lakh.

(a) heat(q) = mass x specific hea capacity x ∆T 

221.4 = 30 x c x 3 

c = 221.4/90 = 2.46 Jg^-1 K^-1 

(b) molar heat capacity = 2.4 x 46 = 110.4Jmol^-1 K^-1 .

• The gymnosperms are naked seeded plants 
• Gymnosperms include medium-sized trees or tall trees and shrubs. 
• Roots in some genera have fungal association in the form of mycorrhiza (Pinus), while in some others (Cycas) small specialized roots called coralloid roots are associated with N₂- fixing cyanobacteria. 
• The stems are unbranched (Cycas) or branched (Pinus, Cedrus). 
• The leaves may be simple or compound. 
• The leaves in gymnosperms are well-adapted to with stand extremes of temperature, humidity and wind.
• In conifers, the needle-like leaves reduce the surface area. 
• Their thick cuticle and sunken stomata also help to reduce water loss. 
• The gymnosperms are heterosporous; they produce haploid microspores and megaspores. 
• The two kinds of spores are produced within sporangia that are borne on sporophylls which are arranged spirally along an axis to form lax or compact strobili or cones. 
• The strobili bearing micros porophylls and micros porangia are called micros porangiate or male strobili. The micros pores develop into a male gametophytic generation which is highly reduced and is confined to only a limited number of cells.  
• The cones bearing megasporophylls with ovules or megasporangia are called macros porangiate or female strobili.
